I feel your pain (in my best Clinton voice). It's the reason I never enter contests. Most places who run a contest are doing it for some kind of benefit. Otherwise, why would they go through all the trouble? While you have printed the rules and entry info from their site from last year, and it says nothing about the images becoming the property of the site owners, I suspect you will still have a problem proving it didn't say it somewhere on some other obscure screen buried in their site. Best you might be able to do is nag and threaten them to death and get them to send a few dollars your way. Good luck (but don't let it eat you up)!
