[jQuery] How to show one image at a time using jquery cycle plugin?

Hi

I have 8 images but before the cycle(scrollUp) start, the first 4
images will display and then it move up one image at a time, and cycle
through to the next image....

Like this:

(img1-img2-img3-img4) then (img2-img3-img4-img5) then (img3-img4-img5-
img6) then (img4-img5-img6-img7) then (img5-img6-img7-img8) .....

Anyone can help?

Thanks!
