Before and After Pics
It looks like you go to the top and click "Photos" then click "Before and Afters" then in the new page right under the picture it says "Want to submit your Before & After photos? Click Here". Here's the link. I assume you just need to follow the instructions after that.
I haven't done it but I looked to try to help you :) I hope it helps.
