The gallery app has been modified to be gallery field to allow adding multiple galleries per entry.
Gallery field allows you, to put sobipro image fields together into many types of galleries defined in the field configuration page.
also you have the option to set image size, container dimensions and which images to show into the gallery.
This this a reliable gallery application for Sobipro, very easy to install and configure, at first had some css conflicts and Mostafa (developer of this application) helped to solve it in a blink of an eye, He offered a high level support. I recommend it..
