This has been discussed before.
My opinion is that it is difficult to implement ...
Like you say you need to keep several versions of each file.
Not only that, for each HTML page you need to keep the appropriate
images.
This means that some sort of re-writing of links to images.
But then the same image might be used for several versions of the same
HTML file so you can't have a unique set of images for each HTML file,
there is some sharing.
Also a link on a site to "todays_news.html" needs to only link to the
specific version of that page from the same day or you get confusion.
If you follow this through then you either end up with a very
complicated system of links to different URLs or you have to live with
something that can serve up misleading sets of pages and images.
