Component Help

Where can I find a code for the banner? I can't seem to find it anywhere.
I don't want to make changes to my LJ, I just want a code for the banner so I can add it to my LJ

Thanks! :)

Hey I was wondering where do I find the tab on the Component wizard to change the pixel size of my template. Also I was wondering if I could edit the "free text" box in wizard or would I have to go into the other codes to edit that. Thanks.
