calling a PHP file in the src of an image

[eluser]dennismonsewicz[/eluser]
I am using an image resizing function and cannot get the images to display at all, but I can go to the image directly in the browser and see the image...

here is how I am calling the function:

Code:

<img src="imageresize.php?maxsize=xxx&source=path/to/image/file" />

but that is not working!!!
