Thanks for that.
In my pages I provide the equivalent text in visible words so that people
visiting the page can see the words just as the spiders can.
Then when (eg) Google finds the page with the phrase sought, this phrase
shows in the search result paragraph. I don't recall such a paragraph
providing a search return for an alt tag; maybe they are rare.
