I'm lucky, I don't get many! Usually, just a family photo of my brother, wife and two daughters, and this year, a photo of my English niece and nephew (he's just under a year old).
Brother's family photo will end up getting tossed eventually.
The niece and nephew's photo? I put it in the same frame as last year's photo of niece - the old photo moves to the back. And I'll just keep adding photos to the front as time goes by. I used to do this with one photo a year of each of my kids...eventually, the photo frame couldn't hold them all, but it's a good way of seeing how children you ARE close to change form year to year.
