We fixed a bug which caused the FactBall game graphics to appear in the users picture Gallery for the Nook Color. The fix addresses new downloads, but does not solve the problem for people who have already downloaded the game.
However, we have put together a PDF document which describes how to remove the images from your Gallery using your PC. You can download the instructions at:

Also note that if you delete the images out of your gallery manually, they will be deleted from the game as well. In order to restore them you will also need to follow the directions in the PDF document.
We apologize for this mix-up.
