I don't buy them all but I do get them for milestone years (start/end school type thing). I generally only buy the picture and the mount and they're currently just propped on a shelf in my sitting room. I'm thinking of getting some frames. I've always felt they're a bit naff but actually I love looking at them because my DC make me swell with pride and it's not often they'll pose for a photo.
What do you do with yours?
