Set limits on the number of merge images and their dimensions on canvas

[Haris Pobric]

Is there a way to

1. Set a limit to a number of images that can be added to the canvas (in this case, we would not be using templates or pre-set images as per the demo examples), and
2. Pre-determine the dimensions of uploaded images upon the initial placement on canvas? The current size is about 85x85px regardless of the size of canvas, and there is no obvious way to modify this in the configs.

Thanks.

I sort of figured out how to address the point 2 in the original post but now wonder if there is a way to use object-fit attribute for the images inside the imageBoxDR elements.
