Well, I just noticed that your signature is out of the limits. It cannot be anything more than 300 pixels in height and 500 pixels in width. Thus, you might wanna try and resize that huge banner. It's like..100 pixels too tall. And well, those sprites can't be left in your signature if you're adding a 500x300 banner into it. Thus, you might wanna do something with them as well.
Just a suggestion as a friend, bro. You don't wanna get into trouble, do you? :3
