Thanks everyone!
Lilro, I like that wood framed one too. I didn't even know they came in non-digitally looking frames, so I was impressed to see those!
Stacey, interesting that you said the 7in one wasn't big enough. Is it 7in from end to end, or is the actual photo 7in?
Jupy, thanks for the tip about Argos. That might actually be where we end up getting the one for DH's parents as Amazon.co.uk doesn't deliver to Ireland.
