Joe Friday,
What I would do is download the image(s), use a graphics program (I use Corel Draw, but I'm sure by now there are some freeware ones that can do the job -- this part of it is basic) to arrange a few of the images as wanted (for example, to make up a wall of a certain size, duplicating the images next to each other, stretching or cropping them as needed), then save each overall surface as an image file (e.g., jpg) and go print it out at Staples (or other places that offer color printing, but that's the one I had experience with). You will want poster paper (not blueprint paper, which is so thin that it will crease due to the color inks), probably matte poly (unless you want a glossy surface specifically, but that will reflect light/glare, which can be a problem when taking photos). They can do any length you might need (the paper comes in a roll), with height up to 36 inches (if not 48?). It is (or was) not too cost prohibitive, either. If I recall (been just over a year since I had something printed), each print (and they have been of varying size) is between $11 and $21 or so.
If you do decide to give this a try, a couple more pieces of advice:
1. For rooms of relatively small/middling size, print separate wall and floor surfaces, mount the wall surface to a foam board or cardboard with tape or magnets, prop it up, and you get a realistic 90-degree angle between floor and wall.
2. For "outside" scenes or very large rooms/halls, have the background/horizon/far wall surface and the floor/ground/foreground surface together as the top and bottom parts of the same single image and print on a sheet as tall as possible (this is where 24, 36, or 48 inches come in handy); then prop up the background end on a foam board or cardboard, with the floor/ground end horizontally on the flat surface in front of it, allowing the sheet to fold gradually and without a hard crease between them. It is helpful to have the background part as short as possible (yet tall enough to work as a background for your figures) so that the foreground is as long as possible (so that you can position the figures far enough from the background to avoid unrealistic shadows). In practical terms, this means at least about 15-16 inches of background (ballpark, I haven't exactly measured it, and it can vary depending on the size, headgear, poses, and placement of your figures).
Hope this helps.
