soring Images

I have created two albums one for outdoor locations and another for indoor locations. Then both are in a Gallery called Locations. But I need to arraign my photos for that the sample images of each location are next to each other. I don’t need the viewer to be able to sort, as this is functioning as a location catalogue for my portrait business. I will be adding images for each location as time goes by. But I don’t see any way to sort the images to keep all the images from one location next to each other.

Does this make sense? Not sure I have explained it well.
