          width=180 border=0> <IMG height=200 src="upimgback/allimg/070325/1529010.jpg"

                        width=200 border=0></MARQUEE>

          图片向右移移动

                   <MARQUEE scrollAmount=1 scrollDelay=60 direction=right

                                              width=160 height=200 >

  <IMG height=200 src="upimgback/allimg/070325/1529010.jpg" width=180 border=0>
  <IMG height=200 src="upimgback/allimg/070325/1529010.jpg" width=180 border=0>
  <IMG height=200 src="upimgback/allimg/070325/1529010.jpg" width=180 border=0>
                                               </A></MARQUEE

           图片向下移动: 

                   <MARQUEE scrollAmount=1 scrollDelay=60 direction=down

                                    width=160 height=200 >
            <IMG height=200 src="upimgback/allimg/070325/1529010.jpg"

                                         width=180 border=0>
            <IMG height=200 src="upimgback/allimg/070325/1529010.jpg"

                                         width=180 border=0>
            <IMG height=200 src="upimgback/allimg/070325/1529010.jpg"

                                        width=180 border=0>
                                        </A></MARQUEE>

       说明:  代码中可以修改的地方

                  direction=right 是移动的方向

上：up   下：down   左：right   右：left 

  scrollamount=5 是向下移动速度，可以调整，

                   一般设置在1---15的范围内比较好。
