[quote]A new issue found:
Someone liked a post of someone else. I wanted to see who. It’s a link wrapped around an image. The image has no alt attribute. Instead it has a title.
Images without alts usually cause an SR to read out the image’s src attribute, as an attempt to read out something useful (even when there’s a title). That URL ending with “661.png” is pretty damn useless though. Title is as usual not available to keyboarders, touch screen users and users of stupid browsers. It’s somewhat more likely people might hear titles if there’s an empty alt="", but the best thing is alt=“user name”. A title could still be there in addition for mouse users if you want.
If we could switch these, it would be nice.
