Here's a resource for writing descriptive alt text:

There's also the tried and true method of listening to blind folks on your timeline and other folks who need alt text! They will tell you what they need and want in alt text.

And here's some nuance (though by no means all the nuance):

I know that there are disabled people who are not able to add alt text to their images.

On some days I am one of those people. On some days I'm the one who needs the alt text, not the one who can write it.

(My disability is dynamic: how severe it is differs from day to day, and some days are Very Bad.)

On days when I cannot write alt text, I choose not to post images and wait for a day when I can. I know that for some people there are no days when they can.

Another choice is to ask for help writing alt text, using #Alt4You or otherwise.

I also know that in desperate moments alt text can seem like too much, even for people who otherwise could write it. I implore you to reclassify alt text as not an extra, but as a central part of messaging, and ask for help: #Alt4You
