I've added one of the built in dnn banners to my page, but I'm having a huge problem.

I'm need to have them left-justified for my client, (very finicky!) and it appears that nothing I do via css seems to fix it.  Looking at the autogenerated dnn code, it throws in this table:

<table id="dnn_ctr518_DisplayBanners_lstBanners" cellspacing="0" cellpadding="0" Summary="Banner Design Table" border="0" style="width:100%;border-collapse:collapse;">
  <tr>
     <td align="center" valign="middle" style="border-color:Black;border-width:0px;width:100%;">
       <span id="dnn_ctr518_DisplayBanners_lstBanners__ctl0_lblItem">
            <a href="/Admin/Vendors/BannerClickThrough.aspx?BannerId=2&VendorId=2" target="_self">
                <img src="/Portals/0/banners/mba2.jpg" border="0" alt="mba2" width="850" height="135">
            </a>
       </span>
    </td>
   </tr>
 </table>

If you look in there, right around the banner span is a <td align="center"... tag that automatically centers the banner.  I've checked in the banner properties and it appears there's no way to change this.  Is this true??  Do my banners HAVE to be centered with DNN??

Thanks,
Victor
