@MelissaBearTrix I have decent, but aging, vision. I use the alt text more often than not.
I think the use of alt text is another example of where, when we help one group of people, we benefit us all. Like letdowns at kerbs and other things.
I won't boost images w/o alt text, but I gave up lecturing about it years ago. I think new fedizens eventually soak into the culture.
Another handy thing about alt text, is that you can translate it.
