Rotating Pictures with PHP
http://discomoose.org/2006/04/28/rotating-pictures-with-php/
Image rotation in PHP is handled by a function called imagerotate(), which takes three parameters (and optionally a fourth, which deals with transparency and is beyond the scope of this guide). The first is the resource identifier which you obtain when you load the original image within your script, the second is the angle which you want to rotate the image and the third parameter is used when the image isn't going to be rectangular, and specifies the colour with which to fill the uncovered areas of the rotated image to make it into a rectangle (since all image formats require rectangular images).

Depending upon how it's done, displaying a page of thumbnail images can be very cumbersome. Allowing the browser to resize images requires the client browser to download the entire, full-size image, then clumsily resize the image to a specified size. This causes the page to load very slowly and creates unavoidable distortion in the resulting images. The other option is to make separate thumbnail images for each individual image. This is fine if you only plan to display a few images, but becomes unrealistic on a large scale or a site involving dynamic images. Fortunately there are ways around these problems using the GD library in PHP.

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).

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.
