@ipg Yes! I asked a question of a poster about their image and they said it was in the alt text and honestly that was how I figured out about alt texts many uses!
And hey #alttext folks. Here's another accessibility hack: your hashtags should use "camel back" lettering. #AltText not #alttext . This is for folks who utilize certain listening aids: without the clear word separation of a capital letter the readers can completely garble the meaning.
