I just don't think you'll get many photos sent in because we already have 1 that someone is hosting. We've already started the voting, and we're moving on to finals pretty soon.

And if you did get a lot, you'd probably get the same photos as the other contest unless someone just couldn't decide for the last one or wanted to change. Thus, getting very similar results.

Maybe you should try to do another type of contest. Fall/Winter/Holidays/something cute/etc.
