Crossfire Costume Contest HELP!!!!

Hi I have a serious issue at hand and I need an answer soon! PLEASE!

So what the problem is is that I submitted a picture to the contest on behalf of this account: RussianSnipe , but what I didn't realize was that I submitted the image on the wrong account!!! I was logged on my secondary account and to make it even worse, IT ALREADY HAS THE GATLING GUN ON IT. I DON'T EVEN USE THIS ACCOUNT! What I'm asking is to see is it possible to submit the SAME image off a different account and over-write the previous submission off THIS account? PLEASEEEE TELL MEEE!!! HELPPP!!! I need to know soon, and I need an answer from a GM or Z8Games Staff please!
