Open the Rich Content Editor
Open Course or Personal Files
You can choose to embed images from Course files  or your personal files . Images in course files will only appear if your instructor has made them public to all users in the course.

You can also use the handles around the image to visually change the image size . To do this, click the image, then hover over one of the white bounding boxes until your cursor becomes an arrow. Drag and resize the image. Please note that the image will always retain its aspect ratio as to not become distorted.
