After a successful edit in Dreamweaver and preview in Google why does my website show a blank page?

38 Critical Code Errors are not helping matters.

You might want to consider using an online website builder instead of MS Word, which is a word processing app.  

Also, image maps are rarely used anymore, and never for something so important as site navigation. 

Using Word to produce code isn’t a good idea. That aside for now...

The link to the image that makes up your page is going to your hard drive, and not the image on the website, so only your computer could ever see it.

Did you make this change to your site without using a Site Definition in DW?

That’s usually what causes DW to use absolute links to your hard drive vs site root relative links like it normally would. In order to work with DW, that is an important first step:

For the time being, you should be able to remove everything from the front of the link before the “images” folder the “file :///C|/” part, and it should come back, if everything is uploaded where it is supposed to be. 

Don’t forget to upload the image itself to your site, DW doesn’t do that automatically when you upload a changed page.
