The page in question can be viewed here: http://quiltersrule.com/beta/index.html and of course just use chrome to view the code.
I noticed that 80% of the time, my 3rd slider image just plain doesn't show. The slider just collapses until it moves onto my placeholder image #4. I have no idea what is going on. The image is the same size as the others, and I don't suspect a loading-time issue.
This only seems to happen in Chrome. I have not tried FF, and it does not happen in IE.
I changed the transition type and it seems to work now.
