About a year ago I created a signature for use in forums. This sig is an image that display's the last 5 tutorials (or tips) that have been approved at CodeDemons. Because I have had many people asking me how I did this, I am going to explain. With this knowledge you can do just about anything with your sig. You will know how to pull any information from a database and drop it in an image. It does not even have to be a signature.

First of all I tried to use Server Side Maps, but I found that they need a Perl script with too many lines of code. So I came to phpbuilder and found an article from Rasmus Lerdorf : Creating Dynamic Images with PHP that shows how useful PHP and the GD library could be for that purpose. Thanx Rasmus!
