Accessibility: Adding alt text to images in scores documentation

[Steph-Chong]

It would be great if alt text could be added to all images (plots, charts etc.) in the scores documentation.

At the moment, I believe all images in the scores documentation are currently from Jupyter Notebook tutorials.

Ideally the Alt Text should work in:

• Jupyter (JupyterLab/Juptyter Notebook)
• Tutorials as rendered in Read the Docs
• Binder

(Note: if I have overlooked any images in the scores documentation that aren't in the tutorials, please post a comment below saying so!)

I did a bit of research on this.

Matplotlib has issue 24309, open as of this writing, to add alt-text to their docs. As near as I can understand, there's a checklist of items needed to make that possible.

Also, note that images can have a title attribute, which is displayed as a tooltip and an alt attribute used in place of the image for accessibility. See usage info here: https://accessibility.psu.edu/images/imageshtml/

@cbare thanks very much for those notes. Sorry I took a little time to circle back to this issue. Knowing about the title attribute sounds interesting, I'm sure this will help out with future investigations.
