Is this more or less meaningful TO YOU than only an image element and req'd attributes? <figure> <img src="images/ennishouse.jpg alt="photo of Ennis House by architect Frank Lloyd Wright"> <figcaption>A photo of Ennis House by architect Frank Lloyd Wright</figcaption> </figure>

I try to make my alt text more descriptive than my captions.

You caught a nuance, you are good! Gold star. Please explain why you do that. Adjacent alt attribute concern: text we add to social media. LinkedIn for one limits number of characters in alt attribute values.

can I offer my reasoning here? I treat alt-text as captions for pictures -- so I like to use it to emphasize certain things... and occasionally to add a bit of snark or humor as appropriate. which is why I wish Twitter let sighted users see alt-text!
