How do I embed images from Canvas into the Rich Content Editor as an instructor?
You can upload image files to your files in Canvas and embed them in the Rich Content Editor. You can also add alt tags to your images for better accessibility.
As an instructor, you have the option to upload images to your course files using the Content Selector. If a change is made to the image in your personal files 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.
Click the Image icon.
Select Canvas Tab
Click the Canvas tab.
Open Course or Personal Files
You can choose to embed images located in your course files  or your personal files . As an instructor, you can embed any image from your files into the Rich Content Editor, even images that are in folders not visible to students.
Note: When accessing course files, students will only be able to see images that are public to the entire course.
To embed a previously uploaded image, click the image you wish to embed.
To upload an image to embed, click the Upload File button.
In the dialogue box, select a file to upload . Then click the Open button .

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 .
