From time to time you may find yourself needing to highlight portions of an image or point out features of a diagram for your students. Or you may want students to do the same. For example, in an photography class you may have students mark an image to illustrate use of lighting and framing. On a Chromebook it's fairly easily to annotate images if you use Google Keep. In the video embedded below I demonstrate how to download images to a Chromebook and how to then annotate them.
