动态幻灯广告图片如何实现?

很简单啊
看你使用什么语言
比如ASP和JS的结合：<%
w=271
h=170
n=34set rs = server.CreateObject ("adodb.recordset")
sql="select top "&num&" * from news where photo<>'' and flag=1 order by isshow desc, istop desc, id desc"
rs.open sql,conn,1,1
if rs.recordcount=0 then
  Response.Write "<BR><center>没有图片新闻！</center>"
elsefor i=1 to rs.recordcount

pic1=rs("photo")
title1=rs("title")
id=rs("id")
rs.movenext
if rs.eof then exit for
pic2=rs("photo")
title2=rs("title")
id2=rs("id")
rs.movenext
if rs.eof then exit for
pic3=rs("photo")
title3=rs("title")
id3=rs("id")
rs.movenext
if rs.eof then exit for
pic4=rs("photo")
title4=rs("title")
id4=rs("id")
rs.movenext
if rs.eof then exit for
pic5=rs("photo")
title5=rs("title")
id5=rs("id")
rs.movenext
if rs.eof then exit for 
pic6=rs("photo")
title6=rs("title")
id6=rs("id")
rs.movenext
if rs.eof then exit for
pic7=rs("photo")
title7=rs("title")
id7=rs("id")
rs.movenext
if rs.eof then exit for 
pic8=rs("photo")
title8=rs("title")
id8=rs("id")
rs.movenext
if rs.eof then exit for
next
rs.close
set rs=nothing
