That's a great question and I don't know if there is a way to look at all your photos. If there isn't a way, here is a workaround: how I find one is this:
In the top right off the screen, go to your contributions. Then click on the show "500" items and then CTRL+F (control button plus F button) and then type in "uploaded." It will jump to the last photo you uploaded. Then just click the next (down) arrow checking each one until you find it.
I'm staying tuned in, in case someone has a way to view my "gallery," - I'd love to know.
