That's pretty neat. Do you essentially loop over a list of images and run the prompt for each, then store the result somewhere (metadata, sqlite)?
If you want to see, here it is:

Here's an example of the kind of detail it built up for me for one image:
It's wrapped up in a bunch of POC code around talking to LLMs, so it's very very messy, but it does work. Probably will even work for someone that's not me.
I'm sure there's a context limit if you have enough images, where you need to start map-reducing things, but even that wouldn't be too hard.
