图片轮播的代码,从第一张可以顺序跳到最后一张,但是最后一张却跳不会第一张,哪里出问题了吗?

<script>var widths=700;var heights=310;var counts=7;img1=new Image ();img1.src=✀image/0签到.jpg✀;img2=new Image ();img2.src=✀image/0辣言辣语.jpg✀;img3=new Image ();img3.src=✀image/0去挑战.jpg✀;img4=new Image ();img4.src=✀image/0广告语.jpg✀;img5=new Image ();img5.src=✀image/0入住公寓.jpg✀;img6=new Image ();img6.src=✀image/0推荐.jpg✀;img7=new Image ();img7.src=✀image/0人像3D.jpg✀;url1=new Image ();url2=new Image ();url3=new Image ();url4=new Image ();url5=new Image ();url6=new Image ();ur17=new Image ();ur18=new Image ();ur19=new Image ();var nn=1;var key=0;function change_img(){if(key==0){key=1;}else if(document.all){document.getElementById("pic").filters[0].Apply();document.getElementById("pic").filters[0].Play(duration=2);}eval(✀document.getElementById("pic").src=img✀+nn+✀.src✀);eval(✀document.getElementById("url").href=url✀+nn+✀.src✀);for (var i=1;i<=counts;i++){document.getElementById("xxjdjj"+i).className=✀axx✀;}document.getElementById("xxjdjj"+nn).className=✀bxx✀;nn++;if(nn>counts){nn=1;}tt=setTimeout(✀change_img()✀,2500);}function changeimg(n){nn=n;window.clearInterval(tt);change_img();}document.write(✀<style>✀);document.write(✀.axx{padding:1px 7px;border-left:#ff0000 1px solid;}✀);document.write(✀a.axx:link,a.axx:visited{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#666;}✀);document.write(✀a.axx:active,a.axx:hover{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#999;}✀);document.write(✀.bxx{padding:1px 7px;border-left:#ff0000 1px solid;}✀);document.write(✀a.bxx:link,a.bxx:visited{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#D34600;}✀);document.write(✀a.bxx:active,a.bxx:hover{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#D34600;}✀);document.write(✀</style>✀);document.write(✀<div style="width:✀+widths+✀px;height:✀+heights+✀px;overflow:hidden;text-overflow:clip;">✀);document.write(✀<div><a id="url"><img id="pic" style="border:0px;filter:progid:dximagetransform.microsoft.wipe(gradientsize=1.0,wipestyle=4, motion=forward)" width=✀+widths+✀ height=✀+heights+✀ /></a></div>✀);document.write(✀<div style="filter:alpha(style=1,opacity=10,finishOpacity=80);width:100%-2px;text-align:right;top:-12px;position:relative;margin:1px;height:12px;padding:0px;margin:0px;border:0px;">✀);for(var i=1;i<counts+1;i++){document.write(✀<a href="javascript:changeimg(✀+i+✀);" id="xxjdjj✀+i+✀" class="axx" target="_self">✀+i+✀</a>✀);}document.write(✀</div></div>✀);change_img();</script>
