if ($beg =="")$beg=0;                                      

if ($end =="")$end=$numitems;                                      

for ($y=$beg;$y<=$end;$y++){                                      

$filelistdata[$y]=$retVal[$y];                                      

}                  //startsparsing through the file list                                      

$x=0;                                      

while (list($key, $val) = each($filelistdata))                                      

{                                      

        // checks if it is a kosher file types                                      

if ($val != "." && $val != ".." && preg_match(getMediaRegex(),$val))                                      

{
