Are you doing this just for MEL practise? Because you could just rename the images so that their file extensions are numbers corresponding the frame number. Like image.0000 image.0001 and so on. Then you could load the first image in to an image plane and animate the whole thing using the frame extension option in the file texture node...

Or is this some other kind of animation where you actually move those images instead of flipping them in front of the camera?
