I’ve uploaded several galleries of images, but there seem to be limited options for how to sort the photos in each gallery.

I’ve placed the galleries in a page (http://www.gsquaredblog.com/portfolio/) and now I’d like to figure out how (if it’s possible) to sort the images in a random order by specific gallery (everything I’m finding online seems to indicate that this is only possible if you let it pull from ALL galleries).

Is this possible? How? Thanks in advance!
