How are image files remediated?
You will learn how image files, like jpg and png are adjusted within Access Hub to make them accessible.
As a standalone file, the image file is considered accessible because it has an Alt Test (Accessibility) description in the metadata for that file. However, if that image is used within an HTML-based Page, Discussion, Quiz or Assignment within your Canvas course, it will still require additional remediation in the form of Alt text.
Note other image types, like gif, bmp, heic, svg, etc. are not able to be remediated at this time by the Access Hub.
After you have uploaded an image file, jpg or png, to your course in Canvas, you need to wait 24 to 48 hours before clicking on the Access Hub menu item to find it remediated.
1. Enter your course and click on Access Hub in the course menu.
2. Click on Review course files link.
3. Locate the image file in the list of files.
4. Click on Review.
1. Click on Close.
2. Returning to your Canvas course, You can see that some of these images are standalone and some are in web pages.
The images in web pages will need alt text.
Article Summary
You have now learned how to publish an image file to Canvas and that a standalone image file doesn't need additional alt text.
1. Open the image file in an image editing app that can view the image's meta data.
In this case, Adobe Bridge is used. This app is free for CSUF faculty and staff.
2. Open Adobe Bridge, select the desired image, and scroll down to Alt Text (Accessibility).
Tip: if you need Alt Text for an image that will be used in a Page, Discussion, Quiz or Assignment, you can copy this Alt Text and then paste it in the Rich Content Editor.
3. Access Hub has written an AI-based description for the image in the Alt Text field.
This description is likely adequate for a standalone file, but you can still edit the alt text here and save the file to update the alt text.
4. Copy the text in the Description field.
5. When in Edit mode for the Rich Content Editor, click on the Accessibility Checker icon.
6. Paste the Description text into the Change alt text field.
7. Click on Apply.
Note that Alt text should be 120 characters or less. If the alt text is longer than, it can be placed as text below the actual image or for very detailed descriptions, it can be placed in an attached file linked under the image.
8. Click on Save down at the bottom of the page.
Now students using screen readers or other readers will have access to the alt text for this image.
