Thanks for picking up on this from our discussion.
Here is a clean way to put that link in your signature.
Edit your sig file and put the following string into it.
(using Ron61's link as an example)
The first part of the string is the link; the second part is what you want the link to read as in the sig.
PHP Code:
[url="http://smg.photobucket.com/albums/v643/Ron61/"]View my Miscellaneous Gallery[/url]
It would display like this:
View my Miscellaneous Gallery
...opening up the external Gallery in a new Window.
Don't forget the quotes around the URL in the string.
