Drop Shadowed Thumbnail Creator
This class allows you to very easily create thumbnails of images, on which you can also apply a drop-shadow effect. You can control the colour of the background so that drop-shadow will fit better onto your page and the size of the thumbnail.
You can resize in an absolute or relative way (to a certain size or by a certain size), both as a pixel number or a percentage.
class.dropshadow.php
The main class file. Version two works considerably differently to version one. To emulate version one, see the 'class.originaldropshadow.php' file below.
