PHP class for basic image manipulation

A class providing a set of methods for doing basic transformation to an image like resizing, rotating and flipping. the class is very small (only about 18Kb in size but still heavily documented) and as i said it only covers some basic methods so don't expect miracles. i use it in favour of many other well known scripts that are hard to install, hard to manage, have a thousand files, many megabytes in size and zillions of methods and functions nobody uses. this is how i do it.
