Help! I will even Donate through Paypal, I only want to make a thumbnail of a picture through php code.

Hi Gang, I am serious, I will send a donation (small- I am not a rich man :o) ) through PayPal, if someone is kind enough to help me out. What I need it to create a thumbnail of an uploaded picture. I am not fussy on how the PHP script accomplishes this as long as it works. I tried running Imagemagick (convert after the file is uploaded) through an exec command with no luck. I would like to have two files in the folder where the image is uploated : image.jpg and imagethumbnail.jpg (I want to creat thumbnails on the fly of pictures users upload). I am running IIS 5, If this is part of my problem I am willing to change to apache. I am sure this is a simple process since it is done all the time. If there are otherways to create a thumbnail I am willing to try that as well. I just can not seem to run the convert.exe through a PHP file :o( Is it not possible to run an external progrman (convert.exe) through php code? What I am looking for is some detailed instruction on how to go about this, I have found bits and pieces but there are too many holes in the information I have so far.
