Nasao sam odlicnu galeriju slika za web stranicu, koja radi baš ono šta ja želim. Ideja je bila da skripta prodje po direktoriju u kojem su slike i od slika napravi thumbove i polinka ih na original sliku (i kasnije ce bit dodan lightbox efekt) s mogucnoscu podesavanja izgleda u CSS-u. Nakon par dana trazenja i isprpobavanja sam nasao taman ono sta mi treba, ali s obzirm da se u PHP-u ne sanlazim zanima me moze li se prilagoditi da se slike sortiraju prema datumu kojeg su prebace na server (novije prije, ili starije prije), jer trenutno slike prikazuje po abecedi. Skripta je:

Code:

?php

$columns     = 3;
$thmb_width  = 120;
$thmb_height = 80;

function resizeImage($originalImage,$toWidth,$toHeight){

    // Get the original geometry and calculate scales
    list($width, $height) = getimagesize($originalImage);
    $xscale=$width/$toWidth;
    $yscale=$height/$toHeight;

    // Recalculate new size with default ratio
    if ($yscale>$xscale){
        $new_width = round($width * (1/$yscale));
        $new_height = round($height * (1/$yscale));
    }
    else {
        $new_width = round($width * (1/$xscale));
        $new_height = round($height * (1/$xscale));
    }
    // Resize the original image
    $imageResized = imagecreatetruecolor($new_width, $new_height);
    $imageTmp     = imagecreatefromjpeg ($originalImage);
    imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $new_width, $new_height, $width, $height);

    return $imageResized;
}

function generateThumbnails(){
    global $thmb_width,$thmb_height;

    // Open the actual directory
    if ($handle = opendir(".")) {
        // Read all file from the actual directory
        while ($file = readdir($handle))  {
            // Check whether tha actual item is a valid file
            if (is_file($file)){
                // Check whether the actual image is a thumbnail
                  if (strpos($file,'_th.jpg')){
                      $isThumb = true;
                  } else {
                      $isThumb = false;
                  }

                  if (!$isThumb) {
                      // Process the file string
                      $dirName  = substr($file,0,strpos($file,basename($file)));
                      if (strlen($dirName) < 1) $dirName = '.';
                      $fileName = basename($file);
                      $fileMain = substr($fileName,0,strrpos($fileName,'.'));
                      $extName  = substr($fileName,strrpos($fileName,'.'),
                                          strlen($fileName)-strrpos($fileName,'.'));

                      // Check if the actual file is a jpeg image
                      if (($extName == '.jpg') || ($extName == '.jpeg')){
                        $thmbFile = $dirName.'/'.$fileMain.'_th.jpg';
                        // If a thumbnail dosn't exists tahn create a new one
                        if (!file_exists($thmbFile)){
                            imagejpeg(resizeImage($file,$thmb_width,$thmb_height),$thmbFile,80);
                        }
                    }
                  }
               }
           }
    }

}

function getNormalImage($file){
    $base = substr($file,0,strrpos($file,'_th.jpg'));
    if (file_exists($base.'.jpg')) return $base.'.jpg';
    elseif (file_exists($base.'.jpeg')) return $base.'.jpeg';
    else return "";
}

function displayPhotos(){
    global $columns;

    generateThumbnails();
    $act = 0;
    // Open the actual directory
    if ($handle = opendir(".")) {
        // Read all file from the actual directory
        while ($file = readdir($handle))  {
            // Check whether tha actual item is a valid file
            if (is_file($file)){
                // Check whether the actual image is a thumbnail
                  if (strpos($file,'_th.jpg')){
                    ++$act;
                    if ($act > $columns) {
                        echo '</tr><tr><td class="photo"><a href="'.getNormalImage($file).'"><img src="'.$file.'" alt="'.$file.'"/></a></td>';
                        $act = 1;
                    } else {
                        echo '<td class="photo"><a href="'.getNormalImage($file).'"><img src="'.$file.'" alt="'.$file.'"/></a></td>';
                    }

                  }
              }
        }
    }
}

?>

p.s. znam za mogucnost da je prevarim po sistemu da svaka slika ima 3 broja prije imena, ali mi se ta ideja bas i ne svidja.
