Thank you for all the feedback--The distortions in images on some pages printed from a course while it is running in IE seem to be due to Issues with IE not fully supporting PNGs. The problem only happens here with some printers--I was able to print the same page on three different printers, and on two of them the image was corrupted and on the third it printed fine. It is too bad because I will have to convert my image files --do you think gif format is good for screen shots? (I am creating most of the images in Full Shot, and some in Photoshop)
