.webloc files

URL's saved in a file. File Juicer can only extract the text (which contains the url of course) from webloc files. If you wish to download a web page and the linked files, you can use Safari or FireFox's web archive features

Alternatively, you can also try the Automator Actions for Safari which will let you find links on a web page and downlaod links. They will however not dowload Google image searches!

Microsoft Internet Explorer also saved web archives, and it allows to include linked pages too. File Juicer can extract the images and the html files from Internet Explorers web archives.
