can someone help me delete my picture?

Hello, I am a member of the Gunslinger Girl Up With . com fan site. I had posted a picture I drew there and then removed it because I had preferred to take it down after a while. The problem is that one of the members posted it here because he had wanted to others in the club to see it in my thread rather than in the gallery of that site and in order to do so he decided to post it here. I contacted him and he said that after I removed the picture form the gallery there, he couldn't access it anymore.
I'm hoping someone can please help me remove my drawing.
