Hi olson_jr,
The drag and drop option is a good one. Also, yes, "add media" is what I was wanting to do. Thank you for the pics showing the steps. It took me a few different tries to get it right, but I got it. It seems like one should be able to do it using one of the little clickable camera icons. Would never have looked for "add media" as the button/label for adding an image. But that's an interface/interaction issue, which is what I do for a living. It's not very apparent or intuitive, IMHO.
Now I can add more, just for kicks & giggles. Thanks again.
