Hey Steve, here’s how to do a nice gallery. Click on Add Media just above here. Then Create Gallery, then add the images you want, then click the big ‘Create a New Gallery’ button (bottom right). Then (important*) change the size to ‘large’ instead of thumbnail. Then click ‘insert Gallery’ and you’re done! You’ll see, as below, that all the images are grouped together nicely.
