I am looking to add more functionality to my twitpic clone script. Specifically, I would like for users to be able to tag other users on twitter in an image just like on Facebook. Viewers should be able to hover over the image to view the tag names, which will be twitter usernames and link to their Twitter profile page. The tagged usernames should also be listed underneath each image. I basically want the same feature Facebook offers as far as tagging images.
In addition...when people are tagged in an image, a link should appear on the the user's Twitter page who uploaded the image stating something similar to the following:
@username @username @username were tagged on [url removed, login to view]
