Your signature should have one of each of these
or two of one of them, depending on where your pictures are coming from (note that they're just examples):
- [ img ] www. yourpictureurl .com [/img]
(this one is if you're linking CC to a URL/website for your picture)
- [ attach ] 123xyz [/attach]
(this one is seen when you upload a picture from your PC)
Look familiar? Sorry if it's a little confusing; this is what the code looks like.
