If you wanted to go after photos for everyone I would agree with you. Probably just as interesting would be grabbing everyone's private messages, and although a large dump, would be nowhere as hard to store. A further option would be to filter whose photos you steal, so you only target celebrities and/or the rich and famous for maximum effect. It all depends on the aims of the hacker, but I would imagine you could make a devastating attack without stealing all of Facebook's data
