You can also use Photo Bucket and the Balto Source picture
uploader to get the link. I use the Balto Source uploader.
;D Though many people don't know how to use it. You can ask
me if you wan't to know how.

You can't put any image online without uploading it, it's
impossible. You need to use a dedicated site (I use http://imageshack.us),
upload your image and put the link that the site will give
you between the tags [img] and [/img].

i mean without the url

I don't believe you can, sorry. But if you need a URL, just
upload it at iaza.com.

All you have to do is get the link of the siggy, and put
"[img]" in front of it, and "[/img]" in back of the link.
Its easy. And you can't do it without the url. ;D
