True, I just thought I'd point this out to the original poster: wget won't do the job all the time. If he needs something that works every time, he'd need to use wget and do some of the work manually in case
element is involved or CSS is being used for images (maybe there are other problems there I haven't thought of?) - or write it from scratch ...
The trick would be going through the HTML and CSS specs and find every different way objects can be referenced/included/linked to etc. I'm sure there's plenty!
