LOL, didn't think this mod would cause minor controversy. Not sure what else to call it, forgive me.

From the release post...

It can be used as a forum signature on forums allowing in signatures.

When you use the BB code [img] tag like so:

[img]http://www.your-domain.com/forum/usersig1.php[/img]

It gets parsed like so, assuming the BB code [img] tag is allowed like above:

<img src="http://www.your-domain.com/forum/usersig1.php" border="0" alt="" />

The usersig1.php script of this mod, once you have it up and running, is a clean script returning a JPG image, so forums allowing the BB code [img] tag in signatures like above (on vB it's vB -> vBulletin Options -> User Profile Options -> Allow [IMG] Code in Signatures) you will see the image onscreen.

Please note that the vB BB code [img] tag in signatures is not the same as allowed vB extensions for attachments. Can't say what other non-vB forums do WRT their signatures.

Thanks to those that have been trying to explain it.
