How to make a custom shape with the ability to add an image.

[APERTUREcomp]

I have this box and inside the gray shape I need to place an image. How can i do this? Because I only have square pictures and just cutting them up is not the answer.

Cut the frame up. Split it into the frame and the grey background. Put the square image between the two layers.
