Retina ready isn’t just @2x anymore!

Thumbnail resolution matches your device’s pixel density. They look as good as possible – without much extra bandwidth cost.

Extra high-density XHDPI display / Retina ready feature

Every thumbnail shown with your new gallery will look stunning on modern devices. Photos appear at the same size but in fact made up of more pixels – exquisite detail. Apple’s “Retina Display revolution” certainly contributed to this trend and it’s common sense to follow it.

When you have more pixels on your screen, why not utilize them all? The custom of using double resolution images evolves rapidly. This is new technology that serves images tailored to your actual device. Can it display 3x or just 1.5x resolution photos? Using just 2x images would be suboptimal in either case so you’d need to create multiple sizes. WordPress Gallery Extra carries out the task for you automatically.There is no need to prepare anything. As long as your source images are fairly high resolution you can sit back and relax.

The gallery display more pixels in the same area resulting in perfectly sharp thumbnails.
All thumbnails are automatically Retina ready as long as the original image has a high enough resolution.
It uses a thing called srcset to serve larger resolution thumbnails, for example 3x images on Full HD 5″ devices.

The bandwidth requirement is not increased substantially due to automatically managed quality.
With WordPress Gallery Extra’s Retina ready feature no upscaling or distortion occurs, ever.
As an alternative, you can use the Photon module of Jetpack by WordPress.com / Automattic which is a free CDN.
