Feature Request: Multiple images

[thesubtleties]

Problem
Some platforms optimize for square or rectangular images. For screenshots of mobile layouts it sometimes makes sense to have two or more images in one screenshot (ie chat open vs chat closed).

Solution
Add ability to include multiple screenshot images over the background, each with a border and aligned with each other, etc. Could be vertical mobile style images only in a horizontal layout or even expanded to allow for grids, etc.

Implementation
Likely could update so that inner components are treated with a gap rather than a margin and then the new component that holds the inner components could utilize current margin implementation when being placed over background - just wouldn't wrap this new component in a frame of its own.

@thesubtleties I can definitely see the multi-image support for mobile platforms. I'll add it in my backlog for now.
I need to do some UI testing to understand where i can fit this in current UI. It needs to be simple & polished.

Since, I won't be available for few weeks. I can't commit to it. Unless i get some contribution help in that period i'll start working on it myself.

lmk if you have any thoughts.
