I would like to use the google maps downloader to save satellite images from google maps (http://www.allallsoft.com/gmd/index.html), but is it legal to use?

This program downloads the tiles and match them. The internet explorer does the same. When I view google maps in internet explorer, it downloads the tiles to "C:\Users\username\AppData\Local\Microsoft\Windows\Temporary Internet Files" and put them together. So it copies imagery to folder and mass downloads them.
