Twitter has recently improved the accessibility of its site. When uploading an image, a user can add
alt text – a short description of the image for people with visual impairments.

If you take a look at the HTML source, you can see that I’ve added a unique string as the
alt text. That should make it easy to search for.
If I search for the text of the Tweet – Twitter finds it without issue.
Here’s my question – should it?
Twitter has an impressive advanced search function – allowing filters by sentiment, date, location, and language. So why not search by image?
