How Do I Annotate Images

Sharing ideas by sharing screenshots  and images is helpful, especially if the screenshot is annotated. It adds clarity and focus to the image and the ideas. Annotating images can be a formative or even summative assessment of student knowledge as they label parts and processes. The image above [click to enlarge] is my annotated screenshot for my JumpStart 2017 class Module 2: Slack. I use a Mac and annotate images in different apps: Preview, Keynote, and SnagIt. Sometimes I use Google Drawing.

Reminder: Always use images that your have permission to use — public domain, Creative Commons, or your own.

The question is: How Do I Annotate Images?

Windows users can annotate images with MS Paint: Here’s a HowTo at WikiHow.


Chromebook, Windows, or Mac users can use Google Drawings or Google Keep. [IOS users can edit in Google Keep, but not Google Drawings.]

In this video by Richard Byrne, see how to get the image from your Chromebook downloads folder and annotate in Google Keep.

In this video by Kelly Hollis, see how to annotate Google Drawings, whether you’re on Windows, Mac, or Chromebook.


On a Mac, use Preview [free and installed already] to markup. adjust, or crop images. The end of this video by Matthew Frattali explains how to markup images or screenshots using Preview. Other ways to edit and adjust images [color, add to, alpha] in Mac Preview are explained in this video by Tricia Goins Also, ScreencastsOnline explain several Mac OS image markup strategies [Preview, Mail, and Photos].

IOS users can markup in Photos as shown here in a video by Cara Smith [I choose this video to show that help videos don’t need to be perfect– just show what to do!]

Also for Windows and Macs, SnagIt [a cost], is excellent. Here’s info with HowTo videos when you scroll down:

SnagIt and the How to Edit Video. Snagit also captures video so you can screencast as well. More Tutorials.


Other Google Drawing Ideas

I found these while searching for help videos for this post, and they’re too good not to share:

Book Snaps by Tara Martin-Use of book cover images is acceptable for book reviews.

A Tutorial on Drawing, Graphic Organizers, etc. by Technology for Teachers and Students

And the best resource: Eric Curts Google Drawing Resources

Now you know!

I hope you find an app that works for you when annotation is needed.
