bug#70871: [PATCH] Show avatars from Libravatar.

[Arun Isaac]

Hi Felix,

> There is also not much to abstract:  It's a single 'img' tag.

Well, it's repeated in three places. So, it's probably worth abstracting
out.

> There is no third avatar.  If you haven't yet followed the CSS with a
> Web Inspector, please look for the 'display: none' for that 'img' tag.
> It comes from here:

I believe the third avatar shows up on smaller screens. Try using the
"responsive mode" (Ctrl+Shift+m) in Icecat to simulate a smaller screen.

>> I also just remembered that the alt attribute of the img tag is meant to

>> avatars.

See https://accessibility.huit.harvard.edu/describe-content-images An
alt text of "A" for "Arun Isaac" would not make sense if read out aloud
by a screen reader. It should rather be "Profile picture of Arun Isaac"
or similar. Perhaps, it should also be marked up with
aria-hidden=true. See
https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Attributes/aria-hidden

I'm not saying the current situation in mumi gets accessibility
right. But, while we are changing things, we might as well get things
right.

I agree. But, I'm mainly trying to remain consistent with the existing
code base.

I am happy to make this change myself.

Sorry, so am I, and so is everyone else hacking away on Guix and mumi in
their spare time.

As a reviewer, it is kinda my job to bring contributions up to shape
before they get applied. I am happy to work in good faith towards that
goal. And, I don't feel I have been particularly picky in my review. The
changes I proposed were pretty reasonable.
