The Moodle Dashboard shows thumbnail images for each course shown in the Course Overview block. Here's how to set an image for your course.
- Go to your course's Moodle site.
- Look for your Administration block, and choose Edit Settings.
- In the Description Section, look for the Course Image upload box. The easiest way to add an image is to drag and drop it from your computer into the upload box.
- Click "Save" at the bottom of the screen. On the Dashboard screen, you should see your new image.
To change the image, you'll first need to delete your existing image. Go back to Course Settings and click the image icon in the upload box.
A pop-up box will have a delete option. Then you can upload your new image.
