I’m editing my web site and it does not preview correctly in my browser. Why?
Many Web site designers/builders work on their site locally rather than directly on the server. Unfortunately, we have heard from a number of people having trouble previewing these local-based sites in their browser. This is a very common issue and can occur with any editor, but it tends to be most pronounced when previewing in Microsoft Internet Explorer mostly due to security settings. The following are a few tips and links I feel may be helpful to those of you facing this problem.
Try Previewing in Firefox (http://www.mozilla.com/en-US/firefox/). There are fewer problems with local content in Firefox.
If the Quick Fix does not work: Publish your site to a Web Server.
Note: You can publish to a Subweb to test your pages.

A More Sophisticated Approach
Install a Web server to your local machine that you can publish your pages to:
XP Home: http://support.microsoft.com/kb/304197
XP Professional: http://www.microsoft.com/windowsxp/evaluation/features/iis.mspx or
Windows Vista: http://technet2.microsoft.com/windowsserver/en/library/10aac45e-e993-42a2-bf93-275375d662631033.mspx?mfr=true
