I'm having some trouble getting an Artisteer skin I designed to work with Mojo.  I followed the instructions for Artisteer theme integration in the documentation here, but for some reason, I'm unable to get the background images to appear in the module container boxes.  This, for example, does not have the background displaying on the Mojo site:
.art-post-tr, .art-post-tl, .art-post-br, .art-post-bl
{
  width: 152px;
  height: 152px;
  background-image: url('images/post_s.png');
}

All other images are working, and their references in the style look the same. I also made sure that post_s.png exists and is inside the images folder. Any hints on what might be happening here? Thanks in advance for suggestions.

Thanks so much, Joe.  You are absolutely right.  I'm an applications developer by day, so I'm not the most skilled with configuring IIS and web stuff.  I assumed that since I was using my own server rather than someone else's hosting environment that I had things running in full trust mode.  I appreciate your quick reply.  A hearty thank you for creating this portal, too!
