If it's not too big, you can use double-sided, padded adhesive tape that is made especially for hanging things.
Even if it is big you can use adhesive pads if the underlying surface is clean and smooth and you buy decent pads. I have a plate glass mirror, 2metres high, 1.5metres wide hung in such a way...
