Here is some follow up information to my original post.
This evening I tried to access the web page from home. In 60 tries I was
unable to reproduce the error (i.e., all images were always displayed
properly).
At the office where I encountered the error I am using IE 6.0. At home
where I am not encountering the error I am using IE 7.0 (i.e., Mozilla/4.0
(compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR
2.0.50727; InfoPath.1))
I did an analysis of the site statistics and found 4 user sessions today
where the user was referred to the site, made multiple requests for the same
question in rapid succession and then left.
This behavior is consistent with the problem I am seeing; that some images
are not being displayed on the page so the user tries to refresh the page
several times and when he is unsucessful, gives up and leaves,
If anyone has time, they can try to reproduce the error by going to

At the office I can always produce an errror within abount 2 dozen tries.
I load the page and then click the HP-12C link near the bottom. I should
see two graphics for Question 10, each with an image of the HP-12C
calculator at the top, followed by images of a set of key strokes.
Sometimes I see both images, sometimes I see one, sometimes I see a partial
image and sometimes I see only the text with no images at all.
I never see a missing image icon (rectangle with a red x), just a gap where
the image should be. As I said previously, if I go into the brower's view
source, I see all of the HTML code to render the image; it's just not being
displayed. If I keep refreshing the page, the image eventually displays.
This problem has me perplexed because I have not encountered it on other
sites. In other words, I can't ever remember going to a site where there
were big blank gaps where the images should have rendered, I've seen
missing image placeholders before but not just empty spaces.
Any thoughts are appreciated.
