If the pictures you have are a reminder of what you went through so I say just burn them. When I left my parents house I didnt bring anything with me and I never went back. I dont have any picture of my time with them and Im happy with that. I agree with Steve, don't let the past rule the present.These pictures, as you describe them, show you as a little boy that has a look of pain on his face even when he fakes a smile. They are pictures of a boy who has been recently or is about to go through more horror. That, I think, is a constant reminder of what you went through.
And I've just discovered how powerful a photograph can be, see my post "A Big Empty Space"But photographs are somehow different I suppose, they are a permanent record of our past, and that is what everything we know today is based upon.
