To remove the two references . and .. (those entries are not blank, but references to the current and the parent directory) in the listing you get as returned from the call to glob() you can simply ignore them when iterating over the result:

<?php
$elements = array();
foreach(glob('../image/imagefiles/*.*') as $key=>$filename) {
    if(!in_array($filename, array('.', '..'))) {
        $elements[] = "'".$filename."'";
    }
}
echo implode(',', $elements);

You probably also want to add some html markup in there and htmlescape() the file names, but this snippet should help to point out how to skip the entries...
