In the e-mail that's sent to you're e-mail address, it usually tells you who rated it, click the link that is sent with the e-mail and it will take you right to the photo that was rated. It's confusing but you'll figure it out soon.
It shows you on the right hand side of the photo, look for 5 gold stars on any photo of yours that was rated.
Yeah, I know. :) But how do you know what rating it was rated? Confusing? Sorry. Lol
