ブロックエディター未対応
恐らく、このプラグインはブロックエディターに対応していないので、Gutenbergでは画像が挿入できないです。 あと、lazyload.jsや"loading=lazy"を使用すると、表示されなくなったり画像下に空白ができてしまったりするバグがあるため、画像表示が崩れます。

Suberb plugin!
Wonderful functionality for a photographer or photo re-toucher / editor. Easy to install and implement, may be caused by another plugin conflict it recently had stopped working. The support was very prompt, the developer was able to solve the issue right away!

Good job
Works fine under WPv5.8 and Enfoldv4.8.6 (little bit tricky with the internal builder but it's ok)

Excellent plugin!
This plugin does exactly what it says on the tin and works straight out-of-the-box. Excellent stuff! Oh, and it also works perfectly on WP 5.7.2 - at least with my current selection of themes.
