我有以下代码:
<%= image_tag iterator.image.url(:small), :class => "img_preview" %>
But the rendered HTML shows:
但呈现的HTML显示:
<img src="/actives/hotels/13/small/clean_wave.jpg?1317675452" alt="Clean_wave">

Your class has to be assigned inside of the brackets to be used as part of the options being passed through. Try:
您的类必须被分配到括号内，以作为传递的选项的一部分。试一试:
<%= image_tag(iterator.image.url(:small), :class => "img_preview") %>
