Easily found the nice How do I create a quiz with a question group to randomize quiz questions? and I like that the "alt tag" is right there on the front to prompt me to write what my image is. Since the answers *are* images, that's important.
Realized I'd forgotten one of my cute number bar images but looks like I have to go out and in to get access to it when making the quiz; it's not updating the "files" catalog on the tab I'm using to make the quiz, though it's updated in the tab where I dropped it in. (Yes, loving drag and drop, too!) ... but it worked nicely. DIdn't lose anything along the way.
So... next question: can I copy a question and edit it (since I'll have exactly the same answers to choose from, but different questions)?
