Mala idea adquirir la versión PRO

Pague la versión PRO, y realmente fue un desastre, mi web tuvo constantes caídas, excesiva cantidad de cache, problemas con el CSS, realmente fue una perdida de dinero en el Plugin

still a good choice

This may not be needed as strongly starting from WP 3.9 but still a good choice for larger flexibility if you don’t want to override gallery code.

Clean code & great performance

Clean code and design and does exactly what it says and then more. Also works well with WP Gallery Custom Links and WP Featherlight (lightbox) plugins. Very good stuff! Thanks, Justin.
