How do I embed images from the web in the Rich Content Editor?
You can use the Rich Content Editor to embed images from the web, or images previously uploaded into Canvas, or images found on Flickr.
The Rich Content Editor is used in features that support the editor (Announcements, Assignments, Discussions, Pages, Quizzes, or Syllabus).
Note: If you want to embed an image not already uploaded into Canvas, you can upload your image through the Content Selector.
Open the Rich Content Editor
Embed External Image
Paste or type in the URL of the image you want to embed .
Include an alternate description in the Alt text field  to improve accessibility. The image's default dimensions will automatically populate the Dimensions . Dimensions are referenced in pixels, width x height.

Edit Embedded Image

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.
Note: The Rich Content Editor does not support image cropping.
