Ofi Khan,
Thanks so much, like I tried to say in my initial question a menu that brings up an easy image library seems. straight forwards. Ideally I'd like to place a gallary on a Page Builder page that I can call up from a button or menu.
I thought (and please remember I'm just learning SP Page Builder) that I should be able to place a Joomla module (Easy Image gallery) as an addon. This did not seem to work. Maybe as an alturnative there is a way to link a menu item to a button in SP Page Builder addons.
Cheers Jack
