The best thing to do regarding the entries would be to get in contact with the submitters, I know that would be a bit more involved but you'd need to have their permission to re-host their images for sure unless you are pulling them straight from the blockchain. I believe that @blueorgy wants to do something like that with Steemimg as well.. And on the steembubble thing, how about using Steem Dollars instead of Steem?

Congrats on your 2nd place! I'll finish sending out the rewards a bit later.
