This has been a pet peeve of mine as well. I've noticed a lot of hair/clothing promos just showing the front of the product. I think there should be 3 base images, front-side-back and then they can get artsy with the rest. I agree on those side images. Also the promos where they seem to be advertising one item but showcasing another. Such as I've seen some hair texture promos where the models appearance distracts from the reason behind the promo. Granted, they're trying to kill 2 birds with 1 stone pretty much.

My 2 cents worth...
