Primary Graphics for use in Moodle Courses

Once you click on an image thumbnail in the top row,
the full size image will appear in the row below.
Depending on the browser (if Firefox), you may need to scroll way over
to get to the "middle" of the row. View the bottom scroll bar to help.
Then right-click the image and "Save Image As" or "Save Picture As"
to download the graphic to your computer.
Then you can upload it to your Moodle course and insert it.
