By default, you can use only one screensaver on Windows 7. However, by using the above program, you can use multiple images downloaded through the program as screensavers. To do this, install Be Mine Screensaver. After you did this, right click on your desktop and select Personalize > Screensaver (from the bottom right corner). On the drop down menu, be sure that Be Mine is selected. After, press the Settings button > Settings again > Show Image - All Images - Random.
