ZenCart 后臺上傳圖片出現Cannot Initialize new GD image stream，一看到這個提示就知道與GD庫有關，查看了下空間配置已經支持GD庫，那該怎么解決呢。

還有一大串提示：

Cannot Initialize new GD image stream

網上搜索了一翻，終于找到了答案：
原因是：admin/includes/modules/new_product_preview.php 文件中的
$im_s = @imagecreatetruecolor( PRODUCT_MEDIUM_SMALL_WIDTH, PRODUCT_MEDIUM_SMALL_HEIGHT ) or die(“Cannot Initialize new GD image stream”);這行代碼中的 PRODUCT_MEDIUM_SMALL_WIDTH, PRODUCT_MEDIUM_SMALL_HEIGHT的值沒有讀取到，是非法值。
解決方案：刪除此代碼中的or die(“Cannot Initialize new GD image stream”);
重新打開后臺看了下，終于可以了！
