I'm very new to DNN skinning, so apologies if this is obvious, but I cannot get a background-image to work in my skin.  I'm starting with the "legacy" method of creating skins, as I can't find much documentation about getting started otherwise. 

I have something like the following:


but graphic.gif refuses to show. I've tried various urls...   The file itself is currently in a folder called images in my skins folder. Looking at firebug it's being read from the wrong url, but what should I use as the url to get this to work?  

I tried that as well, but my skin.css seemed to be ignored; not just this style, but multiple styles in it, which made me think it's not an issue with default.css or any of the other DNN css files overriding my skin.css styles...

If using skin.css do I need a link to it in my .html file?  I tried with and  without (index full.html for MinimalEntropy has a link to skin.css) but both cases none of my styles seemed to work.
