Images are not positioned in slider until page is resized.

[deancvd]

I have a problem with 9 sliders on one page, each slider with between 5 and 12 images, each image approx. 500KB. The first slider is usually fine but the other 8 sliders require the page to be resized or refreshed to view properly. What is the best way to ensure the 9 sliders display and position all images correctly, or is this just not possible. Here is a link that shows the problem i'm having. Any help would be greatly appreciated.
