Double click on the blender.exe file to start.

press ' p ' to play. to pause again press ' p '. 

you can as well change the pictures. Just put the pics u wanted in the folder and change their names to PIC1000.BMP and PIC1001.BMP . 

just take care that the pics are having even number of pixels. !!!

the best is 256 X 256. you can do this with  the help of  PAINT in windows. In the paint window click on Image --> attributes.
in the window that opens give values of 256 and 256 in width and height. While doing this take care that the Units are in Pixels and Colors in Colors.

enjoy.!!!
