"Description not necessary" - is this for screen readers?
Particularly helpful Moodlers

Hello, 

When one checks off the "Description not necessary" box for an uploaded image, is this simply just to allow Moodlers the option to save it without adding text, or does it somehow add information into the image html to to tell a screen reader that the Alt text can be skipped?
