Container background not displaying, but loading

[liunx]

I'm working on a website, and had this problem manifest itself in the past hour although the site has worked perfect for the month that the layout has been up. If you go to <!-- w --><a class="postlink" href="http://www.darrellmoore.com">www.darrellmoore.com</a><!-- w --> just below the navigation there is supposed to be a 300pixel gradient graphic <!-- m --><a class="postlink" href="http://www.darrellmoore.com/img/contentBackground.png">http://www.darrellmoore.com/img/contentBackground.png</a><!-- m -->. For some reason this image is not visible when viewing the site, but if you right click and view background image it will open the file. This is happening in both FF and IE. I haven't made any changes to the CSS file today and honestly am at a complete loss for what is causing this. The CSS file is at <!-- m --><a class="postlink" href="http://www.darrellmoore.com/css/layout.css">http://www.darrellmoore.com/css/layout.css</a><!-- m -->. If anyone could offer some assistance I would greatly appreciate it.The picture link is not working. Did you remove the picture?No the image is still there. I just cleared my cache and was still able to load it.You have a </center> closing tag but no opening tag and it is in the wrong place.
