Image Rating Embedded into Wordpress

Basically, I'm wanting a picture rating script to embedded into my Wordpress blog. I'd like the rating script to be similar to HotorNot.com. I'd like the user database from my vbulletin database to be synced together (If they sign up on the forums, they're signed up with this script, and vise versa). The rating script will be put in it's own directory (let's say /pictures/), but then I'd like a thumbnail of the latest uploaded picture to be put in the blog's main index page saying "Latest Uploaded Picture - Rate Now!". Obviously the idea is to encourage users to rate more pictures. If you're going to be using an already existing HotorNot-like script, and just embed it into the blog, that's fine. Just let me know. I'll need basic admin features like Reviewing the pictures before making them live, deleting pictures, IP logging, and that may be it. Looking forward to working with one of you. -Kyle
