It would make the most sense to store nothing. As far as I can tell, it doesn't return a link to the filtered image or anything, just the binary. RAM would be the limiting factor here I think. The images would need to be decompressed to filter them (unless they're doing something very fancy). Edit: welp, I totally didn't read the OP of this thread. Still, I think the storage costs outweigh the cost of just applying the filter each time. Also, people like to filter their own images. Nobody I know of shoves existing pictures into Instagram.
