$thumb_width = 80;
$thumb_height = 60;
$col = 6;

function resizeImage($originalImage,$tWidth,$tHeight){

list($width, $height) = getimagesize($originalImage);
$xscale=$width/$tWidth;
$yscale=$height/$tHeight;

if ($yscale>$xscale){
$newwidth = round($width * (1/$yscale));
$newheight = round($height * (1/$yscale));
}
else {
$newwidth = round($width * (1/$xscale));
$newheight = round($height * (1/$xscale));
}

$imageResized = imagecreatetruecolor($newwidth, $newheight);
$imageTmp = imagecreatefromjpeg ($originalImage);
imagecopyresampled($imageResized, $imageTmp, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

return $imageResized;
}

function generateThumbnails(){
global $thumb_width,$thumb_height;
if ($handle = opendir(".")) {
while ($file = readdir($handle)) {
if (is_file($file)){
if (strpos($file,'_rg.jpg')){
$isThumb = true;
} else {
$isThumb = false;
}

if (!$isThumb) {
$dirName = substr($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,'.'));

if (($extName == '.jpg') || ($extName == '.jpeg')){
$thmbFile = $dirName.'/'.$fileMain.'_rg.jpg';

if (!file_exists($thmbFile)){
imagejpeg(resizeImage($file,$thumb_width,$thumb_he ight),$thmbFile,80);
