An exciting update to the Gallery Block gives you more ways to show off images in your posts and pages. While this change won’t be available for most folks until WordPress 5.9’s launch in January 2022, we wanted to share some of what’s to come to get you excited about the future.
Style individual images
You can now use the same tools that are available for individual image blocks on each image in the Gallery Block! This added flexibility means you can do more customization – from adding links to each individual image, inline cropping to edit on the fly, apply unique styles for more visually compelling images, and apply an array of duotone filters.
Add custom styles
For more advanced folks who like to go a bit deeper in their customizations, you now have the option to add custom CSS styles per image. This is thanks to the ability to assign CSS classes to each image.
More accessible and intuitive
With this change comes the benefit of improved keyboard navigation and the ability to add alt text right within the block sidebar. You can also drag and drop to rearrange images.
Next steps
This will be available in January with the release of WordPress 5.9. You can check it out now if you’re using the Gutenberg plugin on any of your sites. Read more about becoming an early adopter if you’d like to get ahead.
If you’re a plugin or theme author who has built upon the Gallery Block functionality, be sure to check out this Dev Note detailing what steps need to be taken for compatibility since this is a breaking change.
We’re excited to see the new galleries that these options open up and what ideas you have to make creating galleries even better.
