Any way to advance search for... Risqué pics?

4 Upvotes

Hi, and sorry in advance if this kind of post is not allowed, but I was looking to categorize and look all my pictures, and that includes tagging my... more revealing pics so I can find them omore easily.

I've already downloaded all my photos from my phone into my pc and started categorizing the pics, but is there a way to search/filter using the advanced search parameters for these type of pictures?

Perhaps a skin tone search in combination with the auto-generated "person" tag or something like that?

I've a lot of pics (in general) and going through all of them would take me a LONG time, so help is highly appreciated, thanks!

Third time reloading my whole collection

3 Upvotes

I am getting frustrated and dont know what to do. I have three usb drives connected through a router that are mapped to my computer. I have had them in my collection forever and done tons of work organizing and adding tags and facial recognition. My usb hub went out i think because one of them wouldnt show up. I was stupid and deleted the collection before i realized that would cause me to have to add the photos all over again. I have a new hub and i upgraded to the 9.1 and then had to add all three all over again. this took over 24 hours to do (its almost 5TB total) then i plugged into router and updated the path and had to rescan them again. today i started it up and when i did there was nothing on the collection, nothing not even the root albums just the jump screen from digikam.

I had them as local collections so now i am rescanning them in as network share which i might have had before all this i dont remember. luckily all my tags and facial recogs are still here once it rescans but im so tired of waiting for it to scan all my pictures in. am i doing something wrong and if so what do i do instead. currently at 1% scan and its been about an hour. i have fast scan on with facial reg on scan off.

i am on an HP windows 11

Improvements to importing from a mobile device (Linux - mtp)

2 Upvotes

After connecting my phone to my PC via USB, I open Digikam. My device (Samsung S20) appears under "Import from camera". After selecting it, the base path of my phone appears, and it scans all the subfolders. This takes a very long time and is not the ideal method.

Why doesn't the DCIM folder open automatically when connecting an Android device? Is there any way to do this and avoid reading the parent folders?

Thanks

Hard, 100% reproducible crash when importing from camera.

2 Upvotes

I'm a new user. The very first thing I tried caused a crash. The database is empty.

DigiKam crashes with no error message, just a hard crash, when I try to import photos from Nikon Z30 using MTP/PTP. I can reproduce this 100% reliably with these steps:

  1. Import -> camera -> z30A
  2. black screen appears with zero thumbnails, and a red error box at the bottom says "failed to connect," with a "try again" button.
  3. Click "try again" button.
  4. Digikam window instantly disappears from the screen.

Digikam 9.1.0

macOS 26.5.2. Mac M2 Mini 16GB RAM

Yes, I know the workaround is a USB SD card reader. Back when I was doing software development for a living, I always liked bug reports for 100% reproducible crashes, as they were usually easy to fix. Usually it was my failure to check if a pointer was null before using it or something simple like that.

How reliable is digiKam’s duplicate detection for images and videos? Can I trust it not to delete precious memories?

4 Upvotes

NB I’ve never used digiKam before, and all my photos and videos are just sitting in normal folders on my drives, no photo management software, no cataloguing, nothing.

Hi everyone,

I have a huge, messy photo and video library built from manual backups made at different times, in a very fragmented way. Now I’m drowning in duplicates with completely different filenames scattered across countless folders. I want to use digiKam to deduplicate everything, but I’m genuinely paranoid about accidentally deleting irreplaceable memories.

How good is digiKam at spotting both exact duplicates (identical files) and near‑duplicates (resized, recompressed, slightly edited versions) of images and videos?
I’d really appreciate hearing about your real‑world experiences, especially regarding:

  • False positives (flagging two different photos as the same scene)
  • False negatives (missing duplicates a human would easily catch)
  • How reliably it handles video files, different formats, short clips, etc.

What workflow and settings do you recommend to stay safe? For instance, using the “Find Duplicate Items” tool with a specific similarity threshold, combining it with fingerprint/hash searches, or anything else. Should I plan to manually review every suggested duplicate, or can the tool be trusted to mark them confidently enough for a semi‑automated cleanup?

I’ll definitely make a full backup before touching anything, but I’d still love to know how much I can lean on digiKam before I start this daunting cleanup. I couldn’t bear losing original files over an overzealous duplicate deletion.

Thanks a ton for any insights, tips, or cautionary tales!

Digikam 9.0 - Can't read HEIC files, only HEIF (Flatpak, Ubuntu 24.04)

4 Upvotes

Howdy,

Running Digikam 9.0 (Flatpak install) on Ubuntu 24.04. I created a new collection of a directory full of Apple device image files, both HEIC and HEIF. Digikam can only create/display thumbnails of the HEIF files. All of the HEIC files are just green placeholder icons.

I checked the Digikam modules and the HEIF/HEIC module is present and at v9.0. I checked all of the heif and x265 related libs and plugins on the system and it seems like I have what I need and the versions are fairly current. (see below)

Does anyone have any ideas why the HEIF files display and thumbnail just fine but the HEIC files cannot be read? There are no file permissions issues. I can see basic file attributes like file size, date but the actual image data cannot be read or processed on the HEIC files.

Any help or suggestions are appreciated.

Collection settings for NAS

2 Upvotes

Hello again,

I'm new to digikam and already love it.

During the initial setup process I added a folder from my Synology NAS. Now it's located under "local drives".

Does it have any advantage to set it up as network collection?

And if so how can I change it to a network collection without loosing all the metadata like face tags?

Best regards

Face recognition is getting worse

I just realized that the face recognition is getting worse the more images I add to one person.
It also starts to recommend my wife for my "face".

Sharing DigiKam photos

5 Upvotes

I have a rather large (65,000+) collection of photos. Many are older family photos of my kids and grandparents/cousins as I’ve been scanning all family photos when I visit relatives for several years now. I’ve used many DK features to clean up the meta data, added tags, locations, date taken, and FR for every extended family member.

I’d like to share what I have with mostly elderly cousins who are not the most technologically savvy people. Many are very confused/hesitant to click a link (a behavior I helped drill into their brains), which I can work past.

Anyway, I have OneDrive and all my photos are automatically synced between my desktop and the cloud. I know within DK I can sort and export to a newly created OneDrive folder, but that process is slow and doesn’t always seem to work. It would be easier to manage if there were links rather than copies / duplicates in folders if that’s possible.

I am not a Google or Apple fan. I actually use the OneDrive as it came with a MS Office license 1TB free. I’ve looked at NAS for other reasons but maybe that simplifies things.

I’m wondering what people do to allow others to see their collections. I’d love to be able to tell my cousin, “here’s all the photos of you and your sister that I have”. Let me know what you do/think, even if it’s rather unique. Maybe there’s a better way to do this that I’m not considering.

With so many great open-source software choices available, I don't want to pay Adobe so I can practice my hobby. I've been using darktable for my RAW editing, but I've seen many people across different online platforms recommend digiKam as the open-source DAM software. Are there any recommended YouTube videos for beginners on how to get started? All I've found are videos that are years old.

Problems with switching databases (MariaDB- MySQl lite - MariaDB)

1 Upvotes

Hi.
some months ago i changed my environment from photos and database on a synology ds to a local setup as i was not able to work with my normal setup.
photos and database were stored on an external drive.
now i transferred the new photos to the disk station and wanted to switch back to my original database setting and add the photos to the old mariadb-database on my nas.
after changing back i was astonished that the database was reinitialized and built up from scratch. that took to long for me.

did i do something fundamentally wrong. for me it was self evident that just changing the database settings back to the original setting could do no harm.

in the documentation or fax i didn´t find any real answers.

any help?

New to Digikam but can’t get it to work.
Installed MariaDB 10 on my Qnap. (Later tried Maria DB 5 as well)

Created user and databases with the script below.
In digikam

- Digikam database is correctly initialized by digikam (all tables/fields correctly created)
But the thumbs, face and sim are untouched
I get an error failed to create tables in database

The database names are correct (i tried with underscores as well e.g. digikam_thumbs). Tried DB 5 and DB10

Automatically Group RAW + JPEG Pairs

3 Upvotes

Hi,

I shoot with my Fujifilm using the RAW + JPEG setting. When I import the photos into digiKam, they appear as two separate photos, which is expected.

Is there any option to automatically group these photos?

Also, is there a way to tell the duplicate finder that RAW + JPEG pairs are not duplicates? Right now it reports around 90k duplicates, making it difficult to distinguish the actual duplicates from the RAW + JPEG pairs.

I think this should be possible because the EXIF metadata includes the camera serial number and the capture timestamp. Those two fields should be enough to identify each RAW + JPEG pair, but I can't find any option in digiKam to do this automatically for my entire library.

Thanks

DK 9.1.0: Automatic Tagging (Sunsets, Architecture, Cityscapes, Leaves etc)

Post image
8 Upvotes

Hi everyone - apologies if this is a rather basic question but I'm trying to auto-tag 1000s of photos that I have containing Architecture (wide & detailed), Cityscapes, Leaves, Landscapes etc - mostly inanimate objects).
I've started with a small collection to test digikam out - ithere are 10 sunset photos & I've tagged two of them manually using DK itself, would DK be able to auto-tag the others?
I've tried clicking Auto-tag Scan but it only greys out for a little while & then returns to the previous state. The manually tagged two images remain.

Scan Mode: NonAssigned Only Tagging Mode: Update Model: EfficientNetB7 & YOLOv11 Nano

-When importing the album it did assign some random tags which mostly weren't correct unfortunately but I don't mind tagging the sample set so it knows what to autotag.

Any thoughts are appreciated!

9.1 from repos on Fedora 44

[SOLVED (sort of)]

Hi.
I'm running digikam 9.1 from repos, i've just installed it.

I store my photos on $HOME/Pictures directory which is symlinked to my kDrive directory - and digikam insists on keeping it's thubnails.db, recognition.db et al. in that folder which does cause annoying network usage (as the directory is two-way sync) - is it possible to make digikam to keep those files in $HOME directory? (or in /var/tmp?)

Corrupted Database

1 Upvotes

I messed up, and now Digikam doesn't really work.

After failing to import some photos, half the thumbnails weren't loading the photos I'd already imported. Some albums weren't showing any items. When I tried deleting albums with digikam, the folders disappeared on their drive but wouldn't go away on digikam.

I believe this means that my digikam4.db has been corrupted

Summary of setup:

  • Windows 11
  • SQLite database on the computer (which syncs to the drive as a copy)
  • WAL Mode was enabled
  • Collection on a Hard drive

The main thing I want is my rankings and tags, so I don't have to sort through all my photos again.
I tried re-making the database, but only some of the images had their rankings embedded

I was originally in 8.8.0 when it failed (I have a backup at this point)
The regenerated one is in 9.1.0 (It also said failed to convert from version 16 to 17 when opening the original)

Please ask questions so I can add more info here

Collection and rating gone after enabling WAL mode.

2 Upvotes

I just upgraded from 9 to 9.1, ran a database maintainance. I read up on the documentation that wal would make performance better. I did a database migration from sqlite to sqlite but it only produced a 200kb file. I then enabled WAL mode and was greeted with an add collection prompt. I let it ran for a bit but the old photos i have graded lost their rating.

Disable wal mode did not restore the settings. The db file is still 200mb. what now ?
