You added the [sigimg] code twice, that's why your sig image appeared twice.
I removed the second one and the file address that points to your computer, lol.
Edit: perhaps this is the source of the confusion. You don't need to close the [sigimg] tag, it's standalone
(think of it as a placeholder for your image).
You also don't need to copy/paste the address of the file on your computer, because MT doesn't access your
computer to find the image; it's hosted on the server.
To link to an image, upload in to an image host (there's tons out there) and copy/paste the URL like this:
For the forums (bbCode):
[url=URL OF IMAGE]LINK TEXT HERE[/url] (displays link to image)
[img]URL OF IMAGE[/img] (displays actual image)
For your userpage (HTML):
<a href="URL OF IMAGE">LINK TEXT HERE</a> (displays link to image (opens in same tab/window))
<a target="_blank" href="URL OF IMAGE">LINK TEXT HERE</a> (displays link to image (opens
in a different tab/window))
<img src="URL OF IMAGE"> (displays actual image)
You only need to replace the text in capital letters.
You can't link to images in your signature apart from your signature image (that you use the [sigimg] tag for).
Linking to images in the signature field (via the [img][/img] tags) will result in only text showing up.
