Dream.In.Code Dynamic Signature! (Using New XML API)

Hello everybody!

skyhawk suggested this dynamic signature using some XML thing he just added to the forums that allows almost every page to be turned into XML, including the profile pages...

Anyway, I created this...I know it's incredibly dry, but I can't help it...I'm not exactly a graphics artist

So I'm looking for ideas on improvements! Tell me what you think!

Here's an example:

http://tibialottery.com/dic/217966.png is the image URL, the number is dynamic.

So incase you don't understand, here's Skyhawk's:

(If either of them say there was an error it just means it didn't parse the XML correctly and you should probably reload the page.)

Anyway, tell me what you think!

OH! RIGHT! And you find the profile ID in the URL when you click on your name in the forums...

-- Made it retry 5 times before giving up...
-- Added Moderators, made it remove "s" from end of groups because of inconsistency
-- Made mentors "more blue"

-- Let images be resized via built-in parameters, like so:

The above sets the image height to 110 and width to 500. (I became too addicted to the GD library, please stop me...)

Have suggestions/ideas for the code? Tell me about them too!

Yours,
Shane~
