NextGen Gallery Slider Display Problems

Hello,

I am experiencing problems with our website home page “slider” or “carousel.” We currently use the NextGen Gallery plugin for the slider. I’ve noticed that some browsers (Firefox, IE) have trouble loading the carousel and for a few moments, all of the images “fall out” of the slider frame and display in column format one after the other. To see what I mean by this, please visit http://www.albertametis.dreamhosters.com

Is there anyway to prevent this from happening?

I would deeply appreciate any advice on this matter.

Thank you!
