You can use the Rich Content Editor to embed images from Flickr Creative Commons. You can also add alt tags to your images for better accessibility.
When searching for images on Flickr, search results display images with a Creative Commons public domain license.
The Rich Content Editor is used in features that support the editor (Announcements, Assignments, Discussions, Pages, Quizzes, or Syllabus). 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.
Note: Although an image may appear in the Flickr Creative Commons, not all images have the same license. Some Flickr images require an attribution to appear within the image. You may want to confirm the image copyright before using it in your course. Click the image to view it directly on Flickr.
Open Rich Content Editor

Search for Images
In the search bar , type in a word or phrase to search for images. Then click the Search icon  or press enter on the keyboard. Search results display all related images with a Creative Commons public domain license and may include more than one page.
The images will automatically populate in the pop-up window. Select the image you want to embed .
The Attributes field will populate the Alt text , which is the name of the image, along with the image's default dimensions . Dimensions are referenced in pixels, width x height. For better accessibility, change the Alt text to an alternate description that describes the image.
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
To change the image dimensions, type in the number of pixels you would like for the new image width . Then click 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.
