This option will be useful if you don’t want to show gallery thumbnails in your post or on your page, but still want to illustrate your text with images. When this option is enabled, gallery will open in pop-up box window after clicking a link and your site visitors will not be redirected to any other page.
When you enable the option, a short link will appear below. You need to copy it and paste into the post or page body.
You also need to copy and paste to the page content the gallery shortcode
In order to make the function work properly, your post or page body should contain both of the elements.
With this option you may add links to several galleries in the same post or at the same page. You need to make sure that the option is enabled in all of the galleries and all necessary elements are copied into the post or page body.
Here you can see a little example – hope these cuties will make you smile!
