PHP creating a png image - php

Question

I am trying to create a PHP image, although I have come across some problems.
I am trying to add a URL to the php file. The url (global.php) contains information to grab the Username of a specific user and input certain image files into the php image.
But whenever I add the global.php link, the image won't show up.
My main question is, am I able to add links to files, plus add things like echo ' ' ; to the php image file?
