好的，下面是我在商店中使用的Image对象。保持规模-需要GD

<?php
class Store_Model_Image extends My_Model_Abstract

        $basename = pathinfo($old_file, PATHINFO_FILENAME);

        $new_name = sprintf("%s_%sx%s.jpg", $basename, $width, $height);
        if(file_exists(self::PATH . $new_name))
        {
            return self::URL . $new_name;
        }
        else
        {
            list($width_orig, $height_orig, $image_type) = @getimagesize($old_file);
            $img = FALSE;

            // Get the image and create a thumbnail     
            switch($image_type)
            {
                case 1:
                    $img = @imagecreatefromgif($old_file);
                    break;

我在请求时调整图像的大小，因此页面首次加载图像时将被调整为模板所需的大小。（这意味着我不必在每次更改设计时都使共享主机崩溃，而尝试重新生成图像缩略图）

因此，在模板中，您传递了图像对象，并且当您需要图像指针时，

<img src="<?php echo $image->get_image_url(100, 100); ?>" />

您现在有了一个100x100的缩略图，该缩略图会保存到服务器中，以备日后重用
