In the lower right corner you can vote for a pic. The way this is done is very need, it is IN the picture and looks kinda cool. SOme idea for ZP or a plugin?

I like the look of that, but it'd have to be up to the theme designer or the user whether to include a rating like that. I agree, a plugin would be the best way...
