名站网址导航为大驾家提供DedeCMS站点程序站点教程相关的知识，比如织梦程序安装教程,织梦程序系统故障等教程。织梦程序图集中，上传的图片像素宽高小于系统设置定的这个尺寸： 较小的这些图片就会无法生成缩略图，导致图集在网页上缩略图显示X叉号，这应该是织梦程序DEDEcms的一个历史遗漏bug，可用下面相关具体操作方法修复。 /include/helpers/，这个网站文件中搜索，下面的相关具体代码如下：
01 if($srcW<=$toW && $srch<=$toh ) return TRUE;
02 $toWh=$toW/$toh;
03 $srcWh=$srcW/$srch;
04 if($toWh<=$srcWh)
