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.
Learn how to create thumbnail images on the fly using PHP. Furthermore you will learn how to process a whole folder of images and create their thumbnails. Since this requires the GD library, you will need an installation of PHP with at least GD 2.0.1 enabled.
Often, tutorials covering the GD libraries and it's available functions in PHP will show how to overlay text onto images, manipulate images (resize, flip, rotate, etc) or how to dynamicly generate charts or graphs from numerical data. I have not seen many demonstrating how to combine images (or moreso, placing a transparent forground image over a background image).
