Chapter 4: Plug-in 14 - Image Alter

The PHP GD library is so powerful that it can perform a variety of image manipulations you would normally only find in a graphics program. In fact you could probably build quite an advanced image editor using them. This plug-in goes someway towards that by providing 14 different image transformations you can apply to your graphics.
