Changing photo rating

Sorry to bother the powers that be with this minor issue, as I'm sure you have better things to do. Recently I tried to rate the below photo 'great' but think I accidentally rated it 'poor' due to my own ineptitude. If so, is there anyway to change it to 'great', or at least remove the 'poor' rating? I would hate for my accidental photo-bombing to keep a great picture off the front page.

The pic is this one: mountainproject.com/v/10616…

Thanks a bunch, and sorry for the hassle!
