Can't link image directory?

Hi everyone, I have a simple script that scans a directory and will output a list of sub directories as a hyperlink. Script is working fine. Only problem I have is that if there is a subdirectory called "Image", my script won't see it. If I rename that subdirectory to anything else, it will see it. If I use a standard href line to link that "image" subdirectory, that's fine but then it won't show up alphabetically when the other folders are linked. Any ideas? Haig
