This is all thing I can do:

这就是我所能做的:

add .image class to a

添加.image类到a。

<a class="image" href="#"><img src="http://i.stack.imgur.com/Sjsbh.jpg" class="" title="TITLE NEED SHOW ON HOVER" src=""/></a>

replace data-content with title in css:

用css中的标题替换数据内容:

.image:before {
    content: attr(title);
    width:100%;
    color:#fff;
    z-index:1;
    bottom:0;
    padding:4px 10px;
    text-align:center;
    background:red;
    box-sizing:border-box;
    -moz-box-sizing:border-box;
}

finally, add this jQuery code:

最后，添加以下jQuery代码:

$("a.image").each(function(){$(this).attr('title',$(this).find("img").attr('title'))});

Here is an easier way. You just use :after pseudoelement on hover. Pure CSS solution

这里有一个简单的方法。您只需使用:after pseudoelement on hover。纯CSS解决方案

<a href="" class="img"></a>

.img{
  display: block;
  width:200px;
  height:200px;
  background: url('http://i.stack.imgur.com/Sjsbh.jpg');
  background-size: 200px 200px;
  position: relative;
}
.img:hover::after {
  content:'This is a description';
  position: absolute;
  width:100%; 
  height:20%;
  bottom:0; left:0;
  background: rgba(255, 255, 255, 0.8);
 }

You won't very specific. I hope it will help. You can also make a tooltip.

你不会非常具体。我希望它能有所帮助。你也可以制作工具提示。
