There are some tutorials here. And here you'll find a list of photoshop tutorials. If you have further questions, you can pm me or someone else who makes siggies.
ok maybe i wasen't clear enough. What i meant was how do i attach a file, that i already have, to be my signature.
First upload it somewhere, like on photobucket.com. Then simply go to the user control panel, and in your siggy box put : and then between those brackets your image link.
where is the user control pannel? Edit: oops i found it. Mods Please delete this post if it seems like spam.
ucp.php And the link for the siggy part : ucp.php?i=profile&mode=signature And if you want to find it normally, it's under the ''board index'' and ''the latest''. Only when you're on the main page though.
