Thank you all for your responses. The problem is now half solved. In the majority of cases, using a period before the directory path ( i.e. ./directory ) will give me the correct path to the directory I specify from the relative path from the web root.
However, it still will not work with the random_image function I created when called from within the web forum I'm using, which is the PHP based "Simple Machines Forum".
I will take this inquiry to their support forum to see if there is any special considerations about their PHP that I should know about.
Thank you all for your time and explanations. I have learned a lot about the DOCUMENT_ROOT variable.
