Useful Tip:

If you use Firefox or Chrome then installing one of the following extensions will make viewing images in lectures easier.

  • Firefox - Thumbnail Zoom Plus (Not all bordered images will have a zoomed version with this extension, but most will.)
  • Chrome - Imagus (This works better than the Firefox extension.)
