Sorry. I use Drupal and it is probably in the module the size is fixed (image style).
Not by Juicebox.
I will find out.

Well, the problem is that the image format is square.
Eg. "Large" = 2048x2048 and I can't choose 2048x1365 (2X3 ratio)?
It seems that the background always be square

Did not get the example attached correctly. Here it is.

I'm trying to explain it better.
The background is scaled only in width according to the size of the image.
Not vertical.
I want the picture to have the same distance to the background edge both horizontally and vertically.
Hope it makes sense.
Attached one example.

I've installed Juicebox_Pro and it looks like the program works really well.
However, there is one problem.
I only use photo horizontally.
But the background is not adjusted in height to photo.
How is it done?
