Kirby ThumbHash

ThumbHash is an image placeholder algorithm. Placeholders are represented by small ∼28 bytes hashes such as 1QcSHQRnh493V4dIh4eXh1h4kJUI. A demo and more information can be found on the website.

This plugin adds ThumbHash support to Kirby, allowing you to implement UX improvements such as progressive image loading or content-aware spoiler images like Mastodon.

Under the hood, the heavy work gets done by a PHP implementation of ThumbHash by SRWieZ: SRWieZ/thumbhash
