I'm interested in mounting my photos on a rigid backing and hanging them without a frame or glass, probably with some "bumpers" attached to the back to make them float out from the wall like standouts. Are your styrene mounting boards rigid enough to be hung on a wall in this manner or will they warp over time? I'm thinking of mounting photos in the size range of 8X10 or 11X14--or perhaps a little larger.

I'm told that for this type of glass-less mounting, photos should be coated with a protective UV coating. Do you offer such a coating for the photos you develop?
