The folks at MindTapp dropped us a note to tell us about their new iPhone app, PhotoNest [$1.99 - iTunes link], that allows you to easily -- and visually -- post pictures to Twitter:
Twitter is an amazing real time communication tool, but it only sends links to photos and not photos themselves, which isn't very pretty.
We are dedicated to fixing this! PhotoNest is an application that goes through your Twitter feed and looks for photos that your friends have posted. It then pulls that photo out and puts into a nice visual stream of photos from your Twitter friends.
