streaming pictures

I am working on the idea to 'bang-send' pictures to stream them into a movie. At present, I use matrixset and pwindow to display the pictures and I am encountering a problem which is 'jitter' or flickr when sending two pictures consecutive. It seems that the matrix can't hold two pictures unless it is emptied before the arrival of the new picture.
Has someone worked on an idea like that and maybe found a solution to streaming pictures to movie in real time?
