Hello Randal,

Right, the alt-text is the text equivalent for the image. Imagine you
tell somebody through phone what you see: this is the alt-text.

This is the value of the a-tag's title-attribut.

In theory.

In praxis, not every screen reader would speak out title values. Or a
person able to see but browsing with images off would not understand
that the alt-texts are clickable. So, an alt-text like image
description plus " - click for large image" is helpful. I can imagine
another way in adding a notice "Click on any image to see its large
version" before the image list, this would reduce redudancy.
