As for your other questions, I need help with that too!!!!!!
As far as I can understand it, you should go somewhere (for instance Angelfire.com)
where you can upload images.
Then you can check the help link of the Forum to learn how to link the uploaded image.
However, this doesn't really work for me, please, if you know what I'm doing wrong, read and answer my Poll: My New Sig thread
