Image ALT tags
Ability to add pre-selected or custom alt tags to images.
The image Alt Tag feature would enable users to control the images that appear on his/her timeline by muting the words used to describe certain images. For example, I could mute "Thanksgiving, Thanksgiving dinner, Thanksgiving plate..." to prevent images tagged with these terms from appearing on my timeline.
This will also be a huge benefit for individuals with vision disabilities. Should pair well with screen readers.
