PhotoContest Plugin with MultiSite & Multi-DB

Hi,
I have a Supporter that wants to run a photo contest on her blog. Users would upload photos and others vote on them. The only plugin I've found is PhotoContest Plugin ( http://wordpress.org/extend/plugins/wp-photocontest/ ). It looks like it might do the trick, but the uninstall instructions look fairly complicated with table deletions and I'm also worried about security. Has anyone used this plugin or is there a recommendation? I'm using Multisite 3.0.1 with Multi-DB 3.0.1.
Thanks!
Chuck S.
