I was hoping there would be some generic guidelines on how to handle dynamic image generation and img tags but anyway, in short after the image is generated by an external process the script that generates the image contains the following code:

if (-e $IMAGEFILE) {
    print $query->redirect($IMAGEFILE);
    exit;
}

And as mentioned previously, the perl script is called via an img tag.
