@Julesbc it’s actually easier than it was on twitter! on the web: when you put a picture in your post, click the edit button in the top right. Describe your picture. It doesn’t have to be fancy, just what the picture is so if someone can’t see it they know what it is. In the mastodon ‘official’ app the description can be added by clicking at the bottom of the picture before posting, and in ivory you just click on the picture and the box comes up. Now you can do alt text, high five! 😀
