Image Splitter: Split large images in smaller tiles

This class can be used to split large images in smaller tiles.

It can take an image as a GD resource handle or a file in the GIF, JPEG, PNG, WBMP or XPM formats.

The class generates a new image of a given size that is extracted as a tile of the main image.

The extracted tile images can be generated in the JPEG or PNG format and saved to files or generated as the current script output.

The class may also save the whole image tiles to files with a path in a given file name format.
