Ok I just upgraded to PHP5 and started using GD. I have a function that takes an image name, a name for a thumbnail, a width and a height it then creates a thumbnail.

I got the function from here. http://icant.co.uk/articles/phpthumbnails/

I only use the createthumb function and its in a file all by itself. I plug in the variables at the start and then run it from the command line. It works like a champ.

However when I put the function into my functions file and try to run it from the web application it fails. Even if I plug in the vars at the start of the function it fails with this error:

[client 192.168.40.254] PHP Fatal error: Call to undefined function imagecreatefromjpeg()

How is it that the function is undefined? Same server, same directory, same variables. Could it be the user? When I run from the command line I am myself but from the web browser I have different permissions. I am very confused.

Any light you all can shed on this would be great.

Thanks
