Displaying images in descending order

[TuulikkiLaine]

Is it possible to get elements in descending order, as in - if more elements are added (with higher id), they would be prepended to the gallery and shown first? What would be the easiest way to do this? Thanks a lot!

This is the script I use to scan a dir and list images in it. it also extracts data from the exif of the file. but you can delete this if you need.

`<?php
$client = (isset($_GET["client"])) ? $_GET["client"] : ""; // client number

$directory = "directory";
$dirname = $directory . "/" . $client . "/";
$images = scandir($dirname);
//shuffle($images);
rsort($images);
$ignore = array(".", "..");
foreach($images as $curimg){
	if(!in_array($curimg, $ignore)) {
	    
	    $currimage= "$dirname$curimg";
	    
	    
	    //Gets file name
	    $filename = basename($currimage);
	    $author = substr($filename, 0, strpos($filename, '.', strpos($filename, '.')+1));
	        $author = str_replace('.', ' ', $author); 
	    $date = substr($filename, 0, strpos($filename, '.', strpos($filename, '.')+1));
	    $title = $author;
	    
	    if(mime_content_type($currimage)=='video/mp4'){
            $currimage = $currimage;
	    }else{
            // read all available tags into an associative array
            $exif_ifd0 = read_exif_data($currimage ,'IFD0' ,0);
            $exif_data = exif_read_data($currimage ,'EXIF' ,0);
            //error control
            $notFound = "Unavailable";
            
            // Date
              if (@array_key_exists('DateTime', $exif_ifd0)) {
                $camDate = $exif_ifd0['DateTime'];
              } else { $camDate = $notFound; }
            // Exposure
              if (@array_key_exists('ExposureTime', $exif_ifd0)) {
                $camExposure = $exif_ifd0['ExposureTime'];
              } else { $camExposure = $notFound; }
            // Aperture
              if (@array_key_exists('ApertureFNumber', $exif_ifd0['COMPUTED'])) {
                $camAperture = $exif_ifd0['COMPUTED']['ApertureFNumber'];
              } else { $camAperture = $notFound; }
            // ISO
              if (@array_key_exists('ISOSpeedRatings',$exif_exif)) {
                $camIso = $exif_exif['ISOSpeedRatings'];
              } else { $camIso = $notFound; }
	    }
