Not sure if it can be uploaded to the forum directly, but you can always upload it to megaupload or any of the other file sharing sites. Anybody in the forum can then grab it if they would like to.
I think I know the poster you mean. If it is the one I'm thinking of, it was awesome. It had a really cool image of the enterprise on 1 side in full color, and then the opposite side was the same image in 3D. The 3D was amazing, too. I really wish I still had it, but it got damaged years ago during a move.
