Instagram is a cool free photo sharing app for Apple iOS devices. The cool thing about Instagram is that it allows users to shoot a photo and share it after applying a variety of effects or filters. You can share your photos through the Instagram app itself or Facebook, Twitter, Foursquare etc.
You can use the Instragram round button provided here as a badge or to link from your website to the photos you upload to Instagram!
