#overlapthis {
background-image:url("mymessage.gif");
height:100px;
left:50px; /* play around with this */
position:absolute;
top:90px; /* and play around with this */
width:500px;
}
#thebigimage {
background-image:url("bread_wine.jpg");
height:548px;
margin-left:auto;
margin-right:auto;
position:relative; /* and this has to be relative */
width:731px;
}

As you have it right now, the image overlaps already. You just can't see it because you didn't add sizes to your overlapthis div. Try this:
正如您现在拥有的那样，图像已经重叠。你只是看不到它，因为你没有给你的overlapthis div 添加尺寸。尝试这个：
#overlapthis {
background-image: url(mymessage.gif);
width: 500px;
height: 100px;
}
Then add margins (and an position: absolute) to position the image at your desired location.
然后添加边距（和位置：绝对）以将图像定位在您想要的位置。
