I’m not running this contest, but I saw that picture.com was running a contest to win some prizes for submitting photos. Anyone who submits a photo can win the prizes. Also, some of the best pictures will be selected and published in a book of photos! So if you have a good picture, then submit it! You might win a prize and you might get published.

P.S., voting will end soon on the forums contest, so get yer vote in!
