Offline Explorer, wget, WinHTTrack Copier, Teleport.. there are tons of software utilities (both free and commercial) that let you download web pages to your local hard drive - they'll mirror complete websites, image galleries and everything else when your computer is connected to the web. But there are some issues with most of these offline browsers. How do you browse or search web pages once they are saved locally? How do you update the local information when the source data has changed?...
