I think that the contest main images should be used in the contest only but this is just my personal thoughts and was wondering if anybody else had any ideas on the matter
I think it's fine to post as many images made from the starters as you want as long as (a) they don't look the same and (b) there are only two that go in for the final judging. I guess if you don't like the extra ones for whatever reason you can always give them a low vote... but the idea of the contest was to inspire creativity, and we shouldn't be placing a limit on that I don't think.
