I just uploaded my site and some of my images and background do not show up. What's wrong?

As with most webservers, our web servers do not support spaces in filenames. Since most pre-packaged backgrounds have titles like "Light Blue Mist.jpg", the web server is not able to see the background. Rename your image files without spaces, i.e. "LightBlueMist.jpg". You may also be running into a case-sensitivity problem, as web servers are CaSe SeNsItIvE.
