I'm having some trouble visualizing the scenario, do you have a live
example?

Thanks for all this great feedback.

Yes, click, enter, or tap will move the focus to the image and the alt text
for that image.


This is not a tooltip. The region the image displays in is always present,
but the image swaps out when the user hovers, clicks/taps/hits enter on the
trigger link.

Visually it is placed to the right or left of a block of text.

The info isn't essential but it is useful. Also, it would be confusing to
use null alt text on the images - the text links would have nothing as a
target.

I like the suggestion of using aria-describedby and aria-label. That seems
to make the most sense in this scenario. Is that applicable when there isn't
an actual overlay or modal?

Best,

Judith
