Basically if you click the view / hide agent info at the top when the pictures transitions you can see the obvious flaw that occurs.
I'm using the slideUp / Down effect in jquery, and some flash slide show plugin from the net.
It appears that the problem is when the whole image is actually being rendered. In Chrome it works fairly well, the problems are in Firefox and (surprise) IE.
If anyone has any tips or experience with this kind of thing it would be greatly appreciated.
