I don't know if this is the right place for this question, but seeing is how the problem has occurred using quizport, I thought I would post it here. I made several quizzes in a quizport that included background images. When my students were doing these quizzes in a computer lab, the background images failed to appear in the quizzes. When I logged in under my name on one of my student's computer in the lab, the background images appeared as they should.
When I logged on at home as one of my students in the course, the background images appeared normally. When I logged in as one my students in another institution's network, the background images failed to appear again.
Is this something to do with quizport, or am I looking at a network issue, or something else? Any help would be appreciated!
