What about vertical cards only albums?

Probably it's my shooting style, but I've got many vertical oriented cards. If the album contains the vertical cards only, then the Brilliant Gallery doesn't check this and shows them with the ugly spaces between them. The screenshot is attached. These are the test cards only, but it's all seen there. The width/height ratio is 2:3, so the spaces are wider than the cards themselves.

Now the cell width/height ratio is hardcoded probably with the priority of 4:3 horizontal shots, but this is not quite right because the cards, depending on the photographer's equipment and habits, can have any rectangular ratio and can be both vertical and horizontal. It would be useful if it were possible to set the height along with the witdh, so user could choose the optimal screen space fill-in.

Is it too complex or low-level issue to be fixed?

With the best regards, Michael
