图片传输到新服务器后损坏

我有一个使用shopp电子商务插件的WordPress网站，我从MediaTemple移动到HostGator VPS。

链接:http://www.shop.deltagrooveproductions.com

在我把图片转移到商店后，所有的图片都坏了。当您尝试在新选项卡中打开图像时，有PHP错误。此链接例如:http://www.shop.deltagrooveproductions.com/shop/images/2338/TerryHank_GottaBringItOnHomeToYou_AlbumArt.png

有图片存储在数据库中，但我不知道为什么他们没有加载，现在我转移。

下面是Assets.php的源代码

var $mime;

任何想法?
