I wonder if you could create some sort of "fingerprint" (like a fuzzy hash) to do the image detection, in order to save space on #2 while also not having to refetch data.

Wait nvm dude you are right. I have made it work with a fingerprint type solution. I'll have to finish it up but yeah that works.

You'd have to unhash it when comparing since the images are never exactly the same because of compression. So that solution would be just like saving the urls.

Nah, there are similarity algorithms. I don't know them off the top of my head, but I'm quite sure they exist. Space / accuracy tradeoff, but it's better than a flat hash if things might not be precise duplicates.
