Course Presentation: preloading of images
Course Presentations can contain lots of high-res images and depending on the connection, they can take some time to load. Currently, images are downloaded whenever a is displayed. If a slides contains several big pictures, the users have to wait until all of them are downloaded and they also see the pictures being shown step-by-step. It would be better if Course Presentation would preload the images for successive slides in the background, while the user is looking at a slide.
