A couple of things.

First of all, get rid of the '@' before imagecreate(). All it does is
hide error messages (you should never use it unless you have a VERY good
reason to do so - and even then shy away from using it).

Additionally, the "or die(...)" is bad - it terminates processing of the
script immediately, generating syntactically invalid output.

Next, in your php.ini file, ensure the following are set:

error_reporting = E_ALL
display_errors = on

(These should always be on for a development system while display_errors
should never be on for a production system).

Next, this must be in a separate file called from an img= statement, not
in the code with the rest of your page. What happens when you try
to load the image in your browser directly?

And finally, what does phpinfo() show you?
