而且调用图片是用${a.typeImg!site.defImg}取不到图片，是一个大红叉
打印出来的地址是：r/cms/www/no_picture.gif
只有加上${base}${a.typeImg!site.defImg}
这样的话不会显示红叉，但是是取得的是no-picture.gif这个图片，
不知道${a.typeImg!site.defImg}是从哪里取图片的？我在【内容管理】栏目里的“标题图”、“内容图”、“内容”、“图片集”里面都上传了图片的，但是没有一个图片被显示出来？

请教啊请教

作者:${content.author}
如果要取文章中的内容图，使用<img src="${arti.contentImg!}" border="0"/>

你好，我用了${content.author} 
要报错的

我就是想在首页把一个栏目的图文遍历出来而已。。。。

我知道您为什么报错了，您是没有判断作者不存在的情况吧？在${a.author}里面的author后面加个!
