depending on what operating system you have and what type of photos you have stored on your computer you can make your own easy.
take all of the images you want to use and store themin a easy toacces folder on one of your drives (I use the desktop)
right click any where on the desk top and go to properties then screen savers. then click the drop down arrow to select types of screen saver I think it is called my pictures screen saver select that. then go over to browse and go select your folder with all of your pics in it and they should randomly come up.
you can choose on time of picture open, distortion at opening and closing, and weather or not you want file name diplayed.
