I've just added a feature to the photo area lets you view the 30 most recently added photos in the gallery. A while ago I added a number at the top of the page that told you how many photos were in the gallery. But even if you see that number increase it's hard to know which ones are new.
So now you can check out the "latest photos" section to make sure that you're keeping up with everything new.
*note* : Due to the way I have the photo area set up for different browsers, this feature is only available for IE users.
