Who Owns Those Photos You Share from your Phone?

How many times have you snapped a photo with your phone and shared it via a Twitter tweet linking to the photo on Twitpic? Once posted, the photo is viewable by anyone and you do not have much control over how it gets used by other people. But, did you know that Twitpic signed an agreement with a company named World Entertainment News Network (WENN) and that WENN can sell those photos for publication? Moreover, you agreed to this when you agreed to Twitpic’s service agreement.
