That message is just a standard test that JSmol does to determine the
capability of the browser.
If you are using Chrome, you have to specially enable reading of local
files by AJAX. Are you seeing this also on an actual web site?
Do you know about the coverImage business? Sounds like this is what you are
after -- it's built in now to show an image and then later replace that
with the applet. Nothing special on your part to do.
