When you create a course on Eduflow it will automatically get a random course thumbnail. Such as this one:
To change the course thumbnail, click the context menu and select "Edit thumbnail photo".
In the new menu you can shuffle between a set of random images or link to something yourself.
If you don't know how to link to a picture, follow these steps:
- Go to (for example) Imgur
- Upload your picture
- Right click on your image, and press Copy Image Address
- Go back to Eduflow, paste the link you copied in Edit thumbnail photo
- Save your changes
