We all love to post images on social media and often we're trying to figure out how to gain more followers to get more reach. One of the ways you can increase your audience is by adding descriptions to your images so that visually impaired people can enjoy them, too. These descriptions have different names: alt tags, alt text, alternative text, descriptions, or sometimes simply captions. In this tutorial, Allison teaches you how to add alt text in several social media platforms using her iPhone. You also learn how to use a free application called Be My Eyes to add incredibly good captions for your images using AI, saving you the trouble of thinking them up yourself.

One of the things that never ceases to amaze me, is the amount of functionality and utilities built right into OSX.

This week, I take a look at one of the Accessibility tools provided with every copy of Leopard and Snow Leopard - that's VoiceOver 3. Designed to assist partially sighted and blind Mac users, VoiceOver 3 is the latest version of the hugely impressive screen reader utility for the Mac.

With VoiceOver, it's possible to have all the screen elements described and read back to you, using the built in speech technologies. Not to be confused with just Text to Speech, VoiceOver uses the concept of a VoiceOver cursor to highlight individual elements on screen (Text, menus, dock, icons, panels, dialog boxes, pretty much everything!) and have the contents of the VO cursor read back to you.

With a multitude of keyboard commands, you're able to navigate the screen and interact with all the elements exposed with VoiceOver.
