Sounds like it's one panel with several pictures you can cut out? You could work with it a few ways...
You could cut it out, border each piece, and put it back together the same way.
You could just leave the panel as a whole piece and put a border around it.
You could cut out each piece and put enough fabric around them to make them all the same size, even making them "wonky" within the larger blocks, then assemble them with or without sashing.
It would be easier with a photo of the actual panel (or a link to it on a website, or we can even track it down with the info on the selvedge).
And, welcome to the boards! The people here are incredibly helpful
