Question:
Why isn't my background / video / music working?

Answer:
The most common reason for this happening is that the you have not correctly entered your URL or you are trying to use the file from your local computer. Double check the address of your URL to make sure it is correct. If you are trying to host your file from your local computer, then the solution is to find somewhere to host your file. For hosting images try PhotoBucket or Imageshack. For hosting video and audio files, search on your favorite search engine (use the Google search box at the bottom of this page!) for free web hosts, and find a suitable host. Then use the URL to the hosted file. If you are hosting a file on a free web host, and it still isn't working, it is more than likely that you have exceeded your allotted bandwidth or they do not allow those type of files.
