If you need to have a webpage always available, SiteSucker will allow you to download a complete website just by providing its homepage.
SiteSucker obtains the addresses to all of the page's existing resources (images, backgrounds, files) and downloads them to your hard drive.
It is also able to read links to existing files within a Flash animation, although it can't handle Javascript.
You can establish a maximum number of levels and/or files to be downloaded, as well as size maximums or minimums, or specify file formats.
Beware: SiteSucker only examines the following HTML tags: a, area, body, embed, frame, iframe, img, input, link, meta, script, style, table, and td. Links included in other tags will not be processed by the program.
