New Casey Anthony Video & Photos Surface

There appears to be a second Casey Anthony video ... and she's back to being a brunette and says nothing -- again -- about her murdered daughter. A 7-second clip has been posted on Twitter.

Screen grabs from the video are posted on the Twitter page of a person claiming to have seen the video but insisting he/she has no affiliation with Anthony. To the contrary, the person is angry that Casey is allegedly trying to capitalize on the video by selling it.

The person says, "Caylee's blood is on the hands of ANY media outlet paying for an interview/photos."

The person appears to have somehow obtained access to the video.

The person says the video is shorter than 2 minutes -- half the length of her previously released video, in which Casey says she adopted a dog. In the new video, Casey shows off her nose ring ... but the mystery photo poster says she never mentions Caylee.

Casey's video shows her saying, "I just pierced my nose last night. Very excited ... and top of my ear."

And, the person on Twitter has also released even more photos of Casey -- showing her out with friends after, the poster claims, she was released from jail.
