If you would like to insert a link directly to your gallery in the sig, this is how you do it. View the attachment to this post (its a notepad document) and copy that code into your sig. Replace the URL within the code to the URL directly associated with your gallery. You can find this out by clicking gallery at the top, and "my gallery" in the general text links area. Copy the URL in your address bar and replace it with the URL in this code.
HTML Code:
<font size="2" face="Verdana, Arial, Helvetica, sans-serif"><strong><a href="http://www.gmperformancetuning.com/gallery/index.php?cat=10001">Click
here to view my GMPT Media Gallery</a></strong></font>
