How to sort gallery pictures?

So I had a website put together by someone who no longer manages it.. Now i’m trying to figure it out again since it’s been a few years since high school and dealing with code.

Anyway, the code for the gallery is
[hb_gallery number=”30″ size=”col-3″]
my question is, how do I change the order of the pictures? I have tried orderby:”xx” where xx is date,title, or even rand, but nothing makes a difference.

Link to page where you can see that the house pictures are scattered and not in the right order (should be front of house, the inside pictures, then the outside)

Thanks for reading my post.
