Of course no nonsense. Go directly to the code

<style>	#mycon	{	background:url('Tpl/1.jpg');	background-size:400px 400px;	background-repeat:no-repeat;	border-radius: 4px;	border: 1px solid #ccc;	width: 400px;	height: 400px;	}</style><div id="mycon">	原来背景图大小：970*630	这里才是战场,以缩略图的形式来将背景图设置</div>

background-size:400px 400px;

followed by setting the thumbnail width and height.

The effect is as shown below:
