2006-07 Fleer Basketball Forum

Does anyone know how to distinguish the regular rookie cards in 2006-07 Fleer Basketball from the "Wal-Mart Exclusive" variants? I started adding images for what I assumed to be the former last night and noticed that my LaMarcus Aldridge card is different than the one already uploaded here. Mine has a posed studio portrait and the one here has a game-action photo, with different text on the back. But neither version mentions Wal-Mart anywhere that I can see. All of the other scans under the main set are similar posed shots, but so is the only image currently uploaded for the Wal-Mart variant. Compare:
