DYKT you can make an image you are posting on Twitter, Facebook, or Instagram more accessible for those with visual impairment?

On Facebook, you can find the option to edit alt text under the three dots in the top corner of your photo post prior to publishing. Instagram will generate an automatic alt text for your image, but you can edit it under advanced settings before you hit share. If you want to edit the alt text on an image on Twitter, look for the small alt tag on the photo.
