Ich habe ewig mit Costom Post Types herumgefummelt, um einem User die Möglichkeit zu geben, seine Galerie auf seinem eigenen Profil zu editieren. Es war echt grausam. Aber dieses Plugin ermöglicht eben diese Funktion vergleichsweise einfach, aber sehr gut. Vielen Dank an den Entwickler! 🙂 Great plugin and extremely fast support! I fiddled with Costom Post Types to give a user the opportunity to edit their gallery on their own profile. It was really cruel. But this plugin enables this function to be comparatively simple, but very good. Many thanks to the developer! 🙂
