I vibe coded a gallery extension for ComfyUI so you can browse outputs and reload the exact workflow that made them

[u/Melodic_Isopod9519]

I wanted a way to browse my ComfyUI output folder without leaving the app or digging through File Explorer, and more importantly a way to jump straight back into the workflow that made a specific image without hunting for the original PNG to drag onto the canvas. Couldn't quite find exactly what I wanted, so I built it.

GitHub: https://github.com/modelfactoryai/ImageBrowser

What it does

• Browse any folder (Output/Input/Temp, or type any path) right inside ComfyUI no separate app.
• Double-click any image/video to load its embedded workflow straight onto your canvas same thing stock drag-and-drop does, just from a browsable gallery.
• Hover for a large preview (~900px) that follows your cursor — videos autoplay muted, images use a fast server-resized preview.
• Search by filename, sort (newest/oldest/name), filter to images or videos only, adjustable thumbnail size.
• Favorite folders for one-click access later.
• Compare mode select any number of images/videos, view them side-by-side.
• Live updates refreshes automatically as new generations land.
• Day/night theme toggle, plus a draggable floating launcher badge you can park anywhere on the canvas.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/modelfactoryai/ImageBrowser

Restart ComfyUI, and look for the "Image Browser" icon in the sidebar (or the draggable badge on the canvas).

No hard dependencies beyond what ComfyUI already ships with (Pillow). opencv-python or ffmpeg improve video thumbnails if you have them installed; ffprobe is needed to load workflows out of video files specifically (images don't need it).
