This class can resize and crop images to a given size.

It can open a local or a remote image file and resize it to a given width and height.

The class can also add a watermark, crop the image to a given position and convert the image to grey scale.

The resized image is stored in a server cache file. If the resized image is requested again, the class may return request headers stating that it did not change since last modification.
