Thumbnailing Images
The most effective method of decreasing the size of an image is to create smaller versions, or thumbnails, of the original. You may easily create thumbnails with the LIB_thumbnail library, which you can download from this book's website. To use this library, you will have to verify that your configuration uses the gd (revision 2.0 or higher) graphics module.[23] The script in Listing 6-12 demonstrates how to use LIB_thumbnail to create a miniature version of a larger image.
