现在的ecshop  中相册里面的图片没有生成相应的缩略图，如果图片太大就会把页面撑坏掉，下面是ecshop相册生成缩略图的方法：

..找到.\upload\admin\includes\lib_goods.php 这个文件，在295行这里的方法

/**
* 保存某商品的相册图片
* @param   int     $goods_id
* @param   array   $image_files
* @param   array   $image_descs
* @return  void
*/
function handle_gallery_image($goods_id, $image_files, $image_descs, $image_urls)
{
/* 是否处理缩略图 */
$proc_thumb = (isset($GLOBALS['shop_id']) && $GLOBALS['shop_id'] > 0)? false : true;
foreach ($image_descs AS $key => $img_desc)
{
/* 是否成功上传 */
$flag = false;
if (isset($image_files['error']))
{
if ($image_files['error'][$key] == 0)
{
$flag = true;
}
}
else
{
if ($image_files['tmp_name'][$key] != 'none')
{
$flag = true;
}
}

        if ($flag)
{
// 生成缩略图
if ($proc_thumb)
{
$thumb_url = $GLOBALS['image']->make_thumb($image_files['tmp_name'][$key], $GLOBALS['_CFG']['thumb_width'],  $GLOBALS['_CFG']['thumb_height']);
$thumb_url = is_string($thumb_url) ? $thumb_url : '';
}

            $upload = array(
'name' => $image_files['name'][$key],
'type' => $image_files['type'][$key],
'tmp_name' => $image_files['tmp_name'][$key],
'size' => $image_files['size'][$key],
);
if (isset($image_files['error']))
{
$upload['error'] = $image_files['error'][$key];
}
$img_original = $GLOBALS['image']->upload_image($upload);
if ($img_original === false)
{
sys_msg($GLOBALS['image']->error_msg(), 1, array(), false);
}
$img_url = $img_original;

            if (!$proc_thumb)
{
$thumb_url = $img_original;
}
// 如果服务器支持GD 则添加水印
if ($proc_thumb && gd_version() > 0)
{
$pos        = strpos(basename($img_original), '.');
$newname    = dirname($img_original) . '/' . $GLOBALS['image']->random_filename() . substr(basename($img_original), $pos);

$img_url    = $newname;

                $GLOBALS['image']->add_watermark('../'.$img_url,'',$GLOBALS['_CFG']['watermark'], $GLOBALS['_CFG']['watermark_place'], $GLOBALS['_CFG']['watermark_alpha']);
}
