I would start off by creating a recursive function:

function recurseDir ($dir) {

    // open the provided directory
    if ($handle = opendir($_SERVER['DOCUMENT_ROOT'].$dir)) {

        // we dont want the directory we are in or the parent directory
        if ($entry !== "." && $entry !== "..") {

            // recursively call the function, if we find a directory
            if (is_dir($_SERVER['DOCUMENT_ROOT'].$dir.$entry)) {

                recurseDir($dir.$entry);
            }
            else {  

                // else we dont find a directory, in which case we have a file                          
                // now we can output anything we want here for each file
                // in your case we want to output all the images with the path under it
                echo "";
                echo "
".$dir.$entry."
";
            }
        }
    }
}

The $dir param needs to be in the following format: "/path/" or "/path/to/files/"

Basically, just don't include the server root, because i have already done that below using $_SERVER['DOCUMENT_ROOT'].

So, in the end just call the recurseDir function we just made in your code once, and it will traverse any sub folders and output the image with the link under it.
