Flatten img src directory and prefix with server name

[richie_hackett]

The problem
I need to go through each html page in a folder/sub folder and alter
the src attribute to a flat directory structure and prefixed with an
absolute path

To do this I was going to write a simple app but decided instead to try
and use the find and replace in files options in VS 2003.

My issue is that my regex really sucks.

What I need to do is take
<img src="./a/test/img.jpg">
<img src='a/test/img.gif'>
<img src='a/deep/test/img.jpg'>
type url's and replace with
<img src="http://myserver/images/img.jpg">
<img src="http://myserver/images/img.gif">
etc

Any ideas how I could do this?
