"I'm not sure what to put in an ALT for an image of a black widget, other than 'black widget.' When you have a whole page of black widgets, you see the problem."

No, I don't. What is the problem? A black widget picture should have the alt text of black widget.

"But I've been informed now that if each image already has a text caption or description with it, you definitely don't need to repeat that in an ALT tag."

Maybe you shouldn't listen to people with no idea of what they are talking about.
