There is your answer, it will *only* work on an image which has an 
*embedded* thumbnail, which is not many images.

You need to look at the GD or NetPBM or ImageMagick functions for 
resizing images if you want to be able to reliably create thumbnails.

Your images almost definitely *do not* contain embedded thumbnails.
