[jQuery] ie6 and ie7 don't load image well when using Cycle plugin

I found that using cycle plugin by http://jquery.malsup.com/cycle/ is
very nice while seeing the page with FF and the rest. However, ie6 and
ie7 sometime can't load the slide show well. To explain in details,
ie6 and 7 at the firsttime loading page can't load the image for my
website. However the second time i visit the same page with cycle
pluging embedded, it would work fine.

I don't know if someone experience the same problem. I am not sure if
it's about the size of image. Should i reduce it? or i should i move
the javascript code from the header to the body?

Thanks
