marquee标签解决不了我想要的效果，图片滚动有空白，怎么办？

<marquee onmouseover="this.stop()" onmouseout="this.start()" scrollamount="39" scrolldelay="3000" direction="up" behavior="scroll" width="165" height="39"> <ul> <li><a href=""><img src="http://www.35eu.com/images/dh001.jpg" alt="" /></a></li> <li><a href=""><img src="http://www.35eu.com/images/dh002.jpg" alt="" /></a></li> <li><a href=""><img src="http://www.35eu.com/images/dh003.jpg" alt="" /></a></li> </ul> </marquee>
