Hm, it could be that IE tries to reload the picture (which isn't there
anymore because the form-data has been expired). Perhaps saving the
picture temporarly on the server will prevent the problem.
That could be what is happening. I'm generating data for students to analyze on one page with the hidden form and generating a graph of the data with the next page. The only thing generated is the image. If I date/time stamp the image file I could serve that up on the next page...it would be good to get the right graph to the right student. Might be worth a try.
To answer my own post. That works, i.e. creating a jpeg file and then accessing in the next php page. I end up with extra image files created for each student/access but a cron entry should get rid of them...and they aren't all that big. Extra flexibility with a html page instead of just the image. Haven't tested it with Win IE yet though...leave that for Monday
