//dirlist now has all dirs ,i think.Lets weed out those with no jpgs, shall we?
foreach ($dirlist as $eachdir){
$filesineach = GetDirList($eachdir, $allowedExtensions=array('jpg','JPG'));
if (count($filesineach) > 0){
$newlist[] = $eachdir;
}//if count >0
}//foreach
$dirlist = $newlist;

i stuck this code in there, seems to work. Is there a Better Way?
