I think I have this gallery thing worked out. I’m sure I left a few steps out, but this is basically how it works.
You upload images, create a new page, and add the images. Next, you click the “Create Gallery” button at the top left of the screen and decide how you want the gallery to look. Finally, you click the “Create New Gallery” button on the bottom right. Yep – two almost identical buttons on the same screen.
Way to go, WordPress. Clear as mud.
