Помогите найти class для оброботки....
Посоветуйте класс для обработки картинок так что бы все обрабатывал расширения((jpeg,jpe,jpg),gif).Обра атывал масштаб картинок и можно было накладывать на них другие картинки. И что бы он не сильно тяжелый был! Заранее СПС

Класс из DLE вполне удобный.
PHP код:
class thumbnail {
var $img;
var $watermark_image_light;
var $watermark_image_dark;
function thumbnail($imgfile) {
//detect image format
$info = @getimagesize($imgfile);
if( $info[2] == 2 ) {
$this->img['format'] = "JPEG";
$this->img['src'] = @imagecreatefromjpeg( $imgfile );
} elseif( $info[2] == 3 ) {
$this->img['format'] = "PNG";
$this->img['src'] = @imagecreatefrompng( $imgfile );
} elseif( $info[2] == 1 ) {
$this->img['format'] = "GIF";
$this->img['src'] = @imagecreatefromgif( $imgfile );
} else {
echo "Not Supported File! Thumbnails can only be made from .jpg, gif and .png images!";
@unlink( $imgfile );
exit();
}
if( !$this->img['src'] ) {
echo "Not Supported File! Thumbnails can only be made from .jpg, gif and .png images!";

Использование:
include_once ENGINE_DIR . '/classes/thumb.class.php';
$thumb = new thumbnail(картика.расширение); // 1323.jpg
$thumb->size_auto( размер в пиксклях); // 100
$thumb->jpeg_quality( качество ); //10-100
и т.д....
