A gallery in grid layout with its toolbar

Use the gallery toolbar to choose how it looks:

Option Choices

Size Small, Medium, Large
Captions Below, On image, Hidden
Show All images, or the first few with a "+N" tile for the rest

Click Manage images to reorder images, add alt text, or set each image's focal point so the important part stays in view when it is cropped.


Galleries for Readers

Readers click any gallery image to open it full screen, step through the others with the arrow keys, zoom in and download the original.

A before and after comparison

The Before / after layout puts two images on top of each other with a slider readers drag to compare them - ideal for redesigns and renovations.
