What Is the Justified Gallery Block?
The Justified Gallery Block arranges your images in rows and automatically adjust their height to fill the available space, maintaining each image’s aspect ratio while keeping the rows perfectly aligned.
This elegant gallery style was popularized by Flickr, and is often referred to as the “Flickr layout” — a balanced, edge-to-edge design that shows images at their natural proportions without awkward cropping.
Perfect for:
- Landscape-oriented photography
- Event or travel galleries
- Editorial and journalistic image collections
- Full-width portfolios with a modern, professional look
How to Add the Justified Gallery Block

1. Insert the Block
In the WordPress Block Editor, click the ➕ Add Block button and search for “Justified Gallery.” You’ll find it under the FolioBlocks section.
Another option to add the block is to type / followed by the block name (Justified Gallery) from inside the block editor.
2. Upload or Select Images
Once you have placed the Justified Gallery block into the Editor a placeholder will invite you to choose images from the Media Library or upload new ones in order to create your gallery.

3. Adjust Gallery Width & Moving Images
Use the alignment controls in the Justified Gallery block’s toolbar to select Content Width, Wide Width, or Full Width.

Because the gallery images are added as inner blocks re-arranging them is super simple. You can select images at once reorder them later by dragging and dropping directly in the editor or using the List View panel.
