Tinypic posted this on their site:
We heard from many of our users in regards to these changes and we appreciate your feedback. Tinypic has restored linking to your images and enabled uploading. Please rest assured no content was removed from the site. We tried to notify users on Tinypic and requested they move their content to Photobucket. Unfortunately this messaging was insufficient and has taken many of our users by surprise and we apologize. Our intent was to begin combining some of the best features of Tinypic and Photobucket, thereby offering users a better experience. Any changes in the future will be better communicated. Once again, we apologize for the inconvenience.
