Twitter has added a nifty gallery feature to its standard web client, letting you see a gallery of the pictures shared over the service for any user since January this year. Just hit their profile and click on the 'Recent images - view all' link for a different insight into anyone you follow.
In my case, I clearly don't share that many images, and I'm overly fond of showing off restaurant menus when I'm dining out. All of which makes me sound obnoxious and greedy. Memo to self: must take more pictures of kittens, or airports, or something.
