I think I have figured out how to do this. At least, to get a gallery of images to appear on a page. I would love it if I could find a way to add a single image to a post.
At any rate, these are images included in the Featured Photos gallery on my photo site. They are some of the ones I thought were either reasonably decent on their own merits or that helped tell something of a story about what I have been up to. Many of those, for instance, from my recent trip to Mazatlán, are about the people I was with and the things we did rather than being necessarily very art-like.
So I am updating this page today, February 3, as part of the process of getting to know software and just how to get things done between SmugMug, WordPress, and the attempt to do a web site.
