twitphoto

https://github.com/scosman/twitphoto

a gem to generate an image URL from shortened URLs from common photo sharing tools. Supports twitter/photobucket, twitpic, yfrog, instagram and tweetphoto/plixi/lockerz. It also includes support for the twitter gem, which helps with expanding t.co and bit.ly shortened URLs. Flickr is not supported as it would require a service call.
