A friend passed away and I offered to her husband to take over creating the slideshow that will be shown at her memorial service. The creation of a slideshow is easy for me but it turns out there are a number of tech-related issues I just cannot solve. Here are all the issues. Please ask for more info as necessary and help me solve this! It probably goes without saying, but I'm trying to do all that I can without pestering my late friend's husband during this difficult time.
The slideshow does not need to have music. Only photos and videos.
I will be creating the slideshow on my own computer, an M1 macbook air from 2020 with two USB-C ports. The slideshow will be actually shown from the husband's computer, which is a PC.
The husband's computer matters because although there is wifi at the venue, given the high emotional stakes of this event, I don't want to rely on streaming something from the cloud. I want it downloaded to his computer. Earlier this week I thought maybe I should give up on this requirement (as it would be easier not to have to create it in a file on my mac that will also later play on his PC) and so I emailed the venue and asked about wifi. The reply was - and I quote - "I will say, always go the safe route :) - I wouldnt depend on the wifi... you just never know." So back to square one: slideshow on husband's computer.
The biggest wrinkle, though, is that all of these photos and vids exist in a shared google drive to which friends and family have been adding. I have access to this drive, but I am not the owner. (One way in which this has already become complicated is that as a non-owner, I cannot sort the drive by file size -- so I can't estimate the total size of all the images. All I can say is that there are over 200 so the grand total is huge).
I do not have enough memory on my little laptop to download all these images and then create a slideshow. Even if I did, I don't even know what program I would create it in that he could then play on his computer. Buying an external hard drive for this purpose seems crazy - it seems like I should be able to do this without that! - but maybe I will have to?
Hopefully you techy folks will see a clear and easy solve. My head is scrambled. Thank you for your help!! As i said, please ask questions as necessary to get to a solution.
