Help for a coding amatuer

[uberdwayne]

Hey all!

I was excited to see this script here, it looks very useful for what I would need, however, I'm having a hard time trying to "set up" the script.  I'm using a form to upload a photo but then I get the error "Source file name must be specified."

My question is, how do I specify the source file name?

If this seems like a n00b question, I apologize, have only been coding for a short time. Any help would be greatly appreciated.

Hold there one sec, I'll download the code to my phone and give you the line you need

Actually on the page where you can download the script is the following instruction:

Sample usage:
Save created thumbnail on server
http://www.zubrag.com/thumb.php?src=http://www.test.com/test.jpg&dest=thumb.jpg&x=100&y=50
Output created thumbnail to the browser
http://www.zubrag.com/thumb.php?src=test.jpg&x=50&y=50&f=0

Hope this helps!
