 * Hi. I’m trying to install the autoviewer pluging on my website, but I receieve“
   The plugin does not have a valid header” every time I try to upload the autoviewer.
   zip file. Any idea what’s wrong?
 * (Note: I have both NextGEN Gallary and NextGEN FlashViewer activated as I read
   from previous posts that these plugins were required).
