hello I have a bg.png file with balck background with a green cirle divided into 4 quadrants in it. i use this png as a back ground for fixed container. i display some png images inside the circle at specific co-ordinates. the images keep moving as the co-ordinates change. when the image goes outside the circle it should not be seen. or it should disappear. how to do this....do i have to do any masking. i have attached the png file here. any help would be very useful Regards Bhanusree
