    Посоветуйте класс для обработки картинок так что бы все обрабатывал расширения((jpeg,jpe,jpg),gif).Обрабатывал 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:

    $watermark_image_dark;
        
        function 
    thumbnail($imgfile) {
            
    //detect image format

            
    $info = @getimagesize($imgfile); 

            if( 
    $info[2] == ) {
                
    $this->img['format'] = "JPEG";
                
    $this->img['src'] = @imagecreatefromjpeg$imgfile );
            } elseif( 
    $info[2] == ) {
                
    $this->img['format'] = "PNG";
                
    $this->img['src'] = @imagecreatefrompng$imgfile );

    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....
