WordPress Galleries are a great way to tell visual stories with captioned pictures. Galleries are just a simple way of inserting an attractive “gallery” of photos into a post, without having to worry about whether they line up correctly.
It used to be, though, that you couldn’t see the Gallery in your post editor – just a placeholder image. That’s now been improved, so you can see your Gallery in your post. There are also tool now to let you easily rearrange the images.
And finally, if you’d rather see the gallery in a slideshow viewer, not as an array of images, activate the Photo Galleria plugin. That’s switched on here. Once it’s activated, you’ll see a new menu option for it under Settings, where you can control the size of the viewer, and make it play as an automatic slideshow if you want.
