I don't have any photos, but you'd know if you were missing a tab. Along each side of your macbook pro, there are 4 screws that hold the top plate in place. The top plate has corresponding tabs, which are fragile and can break off if you're not gentle enough. I broke the front tabs on both sides (I think they had already been weakened due to bumps those corners have received. The tab on the hard drive side fell into the hard drive bay and under the logic board. If you're missing a tab, the cover will be somewhat loose and you won't be able to reinstall the screw.
