SiteShoter is a quirky little freeware program which could be extremely useful in the right circumstances. It’s designed to take regular screen grabs of any website you choose. It can also be set up to take shots of a list of URLs too, and you can set the intervals at seconds, minutes or every so many hours.
SiteShoter is a small utility that allows you to save a screenshot of any Web page into a file. It automatically creates hidden window of Internet Explorer, loads the desired Web page, and than save the entire content of the Web page into an image file (.png, .jpg, .tiff, .bmp or .gif). You can also use SiteShoter to convert .html file on your local drive into image file.
