I've copied the HTML generated by Sphinx Gallery for nbsphinx (spatialaudio/nbsphinx#666) in order to solve #984.

If I'm not mistaken, the new HTML is something like this:

<div class="sphx-glr-thumbcontainer" tooltip="{{ tooltip }}">
  <img alt="{{ title }}" src="{{ filename }}" />
  <p><a class="reference internal" href="{{ uri }}"><span class="std std-ref">{{ title }}</span></a></p>
  <div class="sphx-glr-thumbnail-title">{{ title }}</div>
</div>

It looks like the title appears three times.
Is that intentional?
Or am I missing something?

I think it is generally important to use good alt text for images, but in this case it seems to me that:

• it is entirely redundant
• the title is meant for the whole page, not necessarily for the specific thumbnail image

I'm not a user of a screen reader, but I have the feeling that the title might be spoken multiple times.

It might be good to use alt="", which means that the image is not a key part of the content and AFAIU, it will not be spoken by a screen reader.

I don't really understand the <span> element within the <a> element, why is the title included there another time?
