The Course Builder's Edit Course page allows you to choose an icon for your course.
If you click the link below the textbox for the Course Icon, you will be taken to a gallery of icons from which you can choose.
To pick an icon, simply copy the name of it. For example, if you want the icon above, all you need to do is write allergies in the course icon box. You do not need the embed code for the icon.
The icon will now show up on your course in the Course Library, as well as on the uLearn reports.
