[thelist] image rotation - asp.net

[Casey Crookston]

Trying to cycle through a series of images on the home page - different
image each time the page is loaded.

This is the original code:

<form runat="server">
    <asp:AdRotator AdvertismentFile="HomeImages.xml" runat="server" />
</form>

This is the xml file:

<Advertisements>
 <Ad>
  <ImageURL>art/image1.jpg</ImageURL>
  <AlternateText>FUBAR</AlternateText>
 </Ad>
 <Ad>
  <ImageURL>art/image2.jpg</ImageURL>
  <AlternateText>FUBAR</AlternateText>
 </Ad>
(.... cut the rest of the adds out)
<Advertisements>

This is the code that is returned:

<form name="_ctl0" method="post" action="default.aspx" id="_ctl0">
<input type="hidden" name="__VIEWSTATE"
value="dDwtMTk2NTM5MTMzNjs7PvL7h0MINHXE+3/XypatNkf1nSgr" />
<a AdvertismentFile="HomeImages.xml" target="_top"><img alt="" border="0"
/></a>
</form>

Needless to say, it doens't work!!!  What am I doing wrong?
