Constant movement

Hey,

i would like the slideshow to be constantly moving.
i got it setup so it shows 5 slides (images) and i would like to see the slider to keep rotating.

now i got animation set to 20 seconds but it starts to move fast and slows down and i would like it to be one constant motion of movement.

Is this possible, and if so, how?

cheers
