I was looking a long time for an easy integration of SmugMug galleries into WordPress.
This plugin does it excellent.
I use it together with the PostSnippets plugin. I created the short code once with the Alpine plugin and copied it to PostSnipets. There I defined 2 variables: The album ID and the album key.
When inserting the short code from PostSnipets, I only have to past the album ID ind key - and I'm done.
Good job, folks!
