Tough question - making images relative to root

Hi, If I save for example a wikipedia page using IE or Firefox, it saves an .html file and also a folder, and all images are inside the folder, and all images in the html code point to that folder. Do you guys know of a way for me to save the webpage in such a way that the images are made all relative to / (root). I mean, the images should be in the same place as the .html file. I can of course edit them one by one (I use dreamweaver CS) but if there was a way for those images to have a relative path or for me to use a program that batch processed them so they became relatie to /, would be great, because I have tons of webpages I need to work with.
