A Daily Kos diarist now reports that
There is no doubt something was posted to Weiner’s yfrog account, and after talking to multiple folks both liberal and conservative, they all claim to have witnessed this picture on Weiner’s yfrog account.

Someone may have photoshopped a screenshot of a yfrog page to make it look like it came from Weiner’s page
It was a good theory while it lasted. … Team Weiner is now left alleging that his yfrog page was “hacked.” There are ways to determine the truth of that, no? …
