>Twitpic’s recently amended terms coincide with the announcement of a new deal which sees the service partnering with news agency WENN to sell on the media photos posted by celebrities on Twitter. The new licensing deal ensures that users retain the copyright but by uploading photos service, the company is able to exploit the photos for commercial gain.

>The only real way to ensure you remain in control of your uploads is to upload images to a private server or use a service such as Mobypicture which says it will not try to profit off the back of your work. But if you’re a user of any of the above apps, or any app for that matter, read the ToS, and if you have any questions, which no doubt many will (including yours truly) contact the creator of application.
