Thumbnails Creation: Generate smooth thumbnail images

This package is meant to generate thumbnails from image files located in a specified directory.

The package comes with a class that can traverse directories and list the files in them to determine which are images based on the file name extension.

A sub-class is capable of taking a list of image files and generate thumbnail images that are stored with a file name based on the path of the original image files, possibly in a different directory that is created by the class if necessary.

The thumbnail images are resized proportionally given a percentage scale value or are constrained to a given width and height values.

If GD 2 support is enabled, the images are processed in true color to provide smooth scaling.
