Right click and save your signature. Go to any image uploader (I use imageshack.us) and upload it.
Go to change your signature in your profile and click on image, then put the url the hoster gives you, then hit image again. If you want to center it click center and make sure it says "center" in front of everything and "/center" behind it { with brackets around it like these [] }!
~~ Thank you!
