End up? That's basically where they started. The popularity of Facebook in its very early days was because they made it easy to "stalk" your friends (and/or crushes) via the photos that they shared.
If Facebook hadn't made photographic integration so central to their platform, I don't think they'd have taken off the way they did.
That's also why they were so scared of Instagram - they knew how powerful a network of photo sharing can be.
