I cant edit the size of my sig picture because there is nothing in the edit box when i attempt to remove the pic....what should i do?

I have never seen anything like that before but you had a sigpic tag. I think you just have to upload a smaller picture. I'd also say that this is a very public forum with many users and many lurkers. It is fine if you want to share personal details and pictures, but I would advise some caution. We have seen various sites take pictures from users and post it on their sites.
