This should have worked. Windows should correct the slashes internally.
Internet Explorer is forgiving of backslashes but all other browsers require 
slashes.

Yes and no. In HTTP requests they get converted to %20 which would 
make "Harvard Five F Schol Pic.jpg" 
become "Harvard%20Five%20F%20Schol%20Pic.jpg". Not a pretty site. Generally 
it is better to either concatenate with camel case "HarvardFiveFScholPic.jpg" 
or use hyphens. Modern thinking is underscores get missread when a link is 
underlined during manual entry.

Your queston was about relative paths. Any path that starts with a drive 
letter is an absolute path in windows. Relative paths start from the current 
directory. With an absolute path when you upload the files to the web how do 
you know they are even on windows let alone on the same drive letter. And 
chances are real good they wont be in the same directory as on your disk.

So modern practise is to create a directory called /images in the same place 
as your HTML files. Then the relative path is images/mypics.jpg. The absolute 
path is /images/mypics.jpg because / is the root of your server path for html 
files. The server root is different to the machine root which may 
be /home/username/www/ , /var/http/ , sites/public_html or anyother directory 
specified by the server. 

Anyway by using "images/mypic.jpg" in HTML it will work on both your local 
computer browser and the Internet. No windows absolute path will work once 
your HTML is transferred to the Internet.
