We do photos of kids on landings and upstairs only. Matching frames like this?

I just put our kid pics in small frames on tables and stuff. I have never liked the huge framed portraits.

I just got some professional (digital) photos of my kids. I am terrible at decorating. How should I display them? Canvas prints along the stairs? Glass frames? Our walls are relatively empty, so I'm open to anything.
