Images may be dragged and dropped directly into the Atto editor if you are using a supported browser (not IE 9, Safari 6 or below or earlier versions of Firefox) and can be dragged and dropped directly onto the course page if the editing is turned on and 'media drag and drop' is enabled in Administration > Site administration > Plugins > Activity modules > Label.3 Uploading and displaying an image from your computer.
