Galleries and Slideshows
Image galleries on WordPress.com are a great way to share your pictures with your friends, family, and your followers. An image gallery will display a set of small images attached to a particular post or page. Readers can click on any image to launch a full-size carousel that allows them to scroll through the entire gallery one image at a time. With the slideshow option, images will automatically move from one to the next after a few seconds.
You have several choices for how a gallery will be displayed in your post: a thumbnail grid layout, a tiled mosaic-style layout, or in a slideshow. All sites default to the thumbnail grid style. You can also style each gallery individually.
Tiled layouts can display in one of three styles: rectangular tiles, square tiles, or circular tiles. Along with looking great, the rectangular and square tiled layouts also have hover-over captions to save space while making captions accessible. (Check out examples of all three layout options in this post.)
To switch to tiled layouts from the default, head over to Settings → Media in your blog’s dashboard, scroll down to “Image Gallery Carousel, ” and select the box next to “Display all your gallery pictures in a cool mosaic.” Note that choosing this option makes this layout the default for all your blog’s galleries, including those you’ve previously inserted.
When clicked, gallery images are displayed in a full-size carousel view, which you can customize from the Image Galleries Carousel section of the Media Settings.
