Hi Dan, That's my late PuppyBear Cooky
I'll give you some specifics: There seem to be two ways of using RokGallery; as a module or through a menu item (without defining a module). I am not sure if this is intentional, since it is rather confusing to me. (Furthermore, the appearance of the gallery is different depending on the method.) I am using the latter method. The gallery (as a data structure) is defined by selecting tags. As soon as I set the tags for some newly uploaded images, and without publishing them, they are showing on the website.
