I'd like to host a photo competition with some of my coworkers, but we have no internal site that would allow voting on photos. Does anyone know of a site that would allow uploading and voting on photos for free?
I believe you could use flickr for that. You can set a group there, post those photos in this group - this means they are all reachable from a single place.
Although Flickr doesn't support voting on photos directly, in stackexchange style - "upvote"/"downvote" you can post the votes in the comments.
Just my $0.02
Edit: I believe it also wouldn't be hard to put together a piece of code that would use flickr-hosted images and allow people to up/downvote on them...
Since this was in internal company competition and behind the firewall. I was able to download TinyWebGallery. Which allowed me to create an easy to use gallery which allows people to vote on the images.
Thanks for everyone's input.
Facebook is a commonly used tool for photo competitions - you can judge it based on the number of 'likes' a photo gets. If you set up a new group, restrict it to those you want to enter, and enable photo posting, that should do what you want. Of course this relies on you all being signed up to Facebook...
