sorry i figure it out again. really really easy:
i really need to know. i got this one script that is alphabetally and minimal. which i luv. but i need it to be numerical because well, if ther is more than 9 images it sorts it wrong with abc order!
$path = $_SERVER[DOCUMENT_ROOT] . '/purchase/item/' . $image."/";
$narray=array();
$dir_handle = @opendir($path) or die("Unable to open $path");
$i=0;
while($file = readdir($dir_handle)){if($file != '.' && $file != '..'){$narray[$i]=$file;$i++;}}
sort($narray[B], SORT_NUMERIC);[/B]//// that is it thanks php cookbook
for($i=0; $i<sizeof($narray); $i++){
echo $narray[$i];//which is the filename
} closedir($dir_handle);
