Imagine 37,000 images being shared every second.
How many of those images do you think are accessible to everyone? We are not talking about classified, private, top-secret images here. We are talking about images available to the general public.
How many of them do you think are accessible to deafblind, blind, color-blind, low-vision, low-bandwidth Internet users?
Why accessibility matters
Screen readers allow users to:
- Read content out loud for hearing people to listen.
- Convert content into refreshable braille characters for deafblind users to feel with their fingers.
Images are a form of content. Regardless of whether it is an abstract image or not, all users have the right to know what content is available to them. That means putting alternative text on every image include any applicable parts of the images.

There’s a popular saying, “Show, don’t tell.”
Deque University provides a certificate for completion for each course in their programs. There’s a debate online regarding whether it matters that someone has a certificate or not. Concerning the debate, my clients find it’s easier to trust my expertise with these certificates.
With that said, I’m displaying my certificate here.
Remember that little tidbit earlier,? 3.2 billion images per day?
By the time you finish reading this paragraph, over 370,000 images will have been shared online.
Obviously, we don’t have the ability to answer that question today. However, if you guessed not all of them, you would be right. However many images that are accessible online, they are a mere drop in the bucket.
Let’s frame that statistic a different way. If all those images were shared by everyone in the United States (which has roughly 329 million people 2 ), that’s 9.7 images per day. If all those people took 3 minutes to add an alt tag to each image, it would take thirty minutes to make all those images accessible.
Granted, it’s not simple as adding an alt tag but it’s a starting point.
Your insights matters
