Graphics: Easy Resize Image
László Zsidi (contact me)
This class can be used to resize images keeping the aspect ratio.
It can open an image from a file or a remote URL and create a resized version of the image that neither the width nor the height exceed a given value.
The class returns a GD image resource handle that can be used to serve the resized image in any format supported by the GD library.
