Gallery vertical display?

The gallery shortcode accepts multiple parameters, as explained here:

If you wanted to create a gallery with a single column and large images, you could use the columns and size parameters, like so:

[gallery columns="1" size="large" ids="xx, xy, xz"]

It’s worth noting that you can’t achieve such results if you use Tiled Galleries. These options are only available if you choose the default “thumbnail grid” gallery type.
