The Rich Content Editor will be discontinued in a future release. Instructors can enable the New Rich Content Editor feature in course feature options.
You can use the Rich Content Editor to embed images from the web. You can also add alt tags to your images for better accessibility.
The Rich Content Editor is used in features that support the Editor (Announcements, Assignments, Discussions, Pages, and Quizzes). If a change is made to the source of your image after it has been embedded, the image you have added to the Rich Content Editor will not be changed.
Open Rich Content Editor
Open the Rich Content Editor using one of the Canvas features which support the Editor.
Embed External Image
Paste or type in the URL of the image you want to embed.
Insert Alt Text
The Attributes field will populate the Alt text field , which is the name of the image. For better accessibility, type a description of the image contents. To add the image as decorative, click the Decorative image checkbox . If the Decorative Image checkbox is selected, the alternative text field is grayed out.
Note: If you want to include an image title, which will appear when a user hovers over the image, embed the image and then switch to the HTML Editor. Title tags must be manually added to the HTML code.
Change Attributes Image Dimensions
The image’s default dimensions will also populate automatically. Dimensions are referenced in pixels defined by width then height.
To change the image dimensions, type in the number of pixels you would like for the new image width . Then press the Tab key on your computer keyboard. Since Canvas maintains the aspect ratio of your image, the entry for the image height will be changed automatically .
Click the Update button.
Note: As a future shortcut, if you do not need to change any of your image's attributes, locate your image and simply double click the name of your image. The image will be embedded directly to your post.

When you edit an existing image, the URL tab will display the location of the web image. The attributes will remain the same across all tabs and can be edited as necessary.
If you want to replace your web image, paste or type in the URL of the image you want to embed  .
Visually Resize 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.
