I have added tooltips to images on my site, most work fine but a couple of pictures will not show the tooltip wording at all - check this page, this image is fine:

but this one doesn't show the tooltip text:

http://anthonyfrenchlimitededitions.co.uk/oxford accessories oxford.html

As far as I can see the set up is the same on both ... any ideas?
