 In the preceding videos, the image of the clock was decorative. You didn't need the image to understand the page's content. Here's a page that describes how your eating habits affect your academic success. It doesn't make a lot of sense, because the images aren't there yet. Let's add the images, which are essential to the content. Click where the first image should go, embed image, and upload to our course files this image, and Canvas puts the file name in as the alt text. Alt text stands for alternative text. Let's do the same for the second image. Embed the image, upload it to course files. It puts in the name of the file as our alt text, update, and save. If a visually impaired student is using a screen reader, it will read the alt text when it gets to the image. Here's what it sounds like right now. Clickable. Instead, have something like this to satisfy your sweet tooth. F1,323,986.jpg. Image. Clickable. Well, that's not very helpful. Good alt text describes the image for someone who can't see it. For the first image, think of how you'd describe the picture in a text message if you couldn't send the picture on your phone. You'd say, it's a picture of two donuts with pink frosting and white sprinkles. Let's edit, click the image, embed image, and set our alt text to be two donuts with pink frosting and white sprinkles. For the second image, we'll change the alt text to read, bunch of grapes, two kiwi fruit, and two bananas. Update and save. Here's what it sounds like now. Food for thought. Heading level one. One way you can be more successful in college is to eat a healthy diet. For example, if you think this is a good breakfast, you are mistaken. Two donuts with pink frosting and white sprinkles. Image. Clickable. Instead, have something like this to satisfy your sweet tooth. Bunch of grapes, two kiwi fruit, and two bananas. Image. Clickable. There, that's much better. You might be thinking, it's a nice idea to add alternative text to your images. No, it's not just a nice idea. It's the law. The Americans with Disabilities Act, the ADA, requires you to make your courses accessible to all students, and adding alt text is an important part of doing that. What if you have a complex graphic that can't be summarized in a simple alt text message? For example, this image of blood glucose levels. We'll put in a short text here. Graph of blood glucose levels. Then make a page that summarizes the graph. And underneath the graphic, link to that page. See a full description of the graph with its data in a table. Highlight that and link it to the Food for Thought graphic page. Save, and now you've described the graph in an accessible way. And that's one of the things you do to make your content accessible by adding alternative text to your images.
