修复一生成手机版缩略图的bug，该bug会导致手机版新上传商品主图不显示的问题

找到admin（你的后台路径）/goods.php

1、找到代码：

                    $gallery_thumb = $image->make_thumb('../' . $img, $GLOBALS['_CFG']['thumb_width'],  $GLOBALS['_CFG']['thumb_height']);
                    if ($gallery_thumb === false)
                    {
                        sys_msg($image->error_msg(), 1, array(), false);
                    }

替换为：

                    $gallery_thumb = $image->make_thumb('../' . $img, $GLOBALS['_CFG']['thumb_width'],  $GLOBALS['_CFG']['thumb_height']);
                    $gallery_pic   = $image->make_thumb('../' . $img, $GLOBALS['_CFG']['image_width'],  $GLOBALS['_CFG']['image_height']);
                    if ($gallery_thumb === false || $gallery_thumb === gallery_pic)
                    {
                        sys_msg($image->error_msg(), 1, array(), false);
                    }

2、找到代码：

$gallery_pic=$gallery_thumb;

请将其删除
