** Using WeBWorK **

Hi Joel,

Make sure that you use "shift reload" on your browser to make sure that the image is not being cached by
your browser. Having said that -- yes the image is also likely
cached on the machine as well. There is some effort made to insure that this image
is "current" but since you are doing something a bit outside the standard box
it's possible that in this case the refresh isn't behaving properly. It would take some experimenting
to figure out exactly what the problem is.

Take care,

Mike
