a picture is worth how much?

Pictures have always been a way to show how things happened in the past or a memory we want to capture. People take them to display their families and friends, to show how we looked then and how the styles have changed, etc.
I don't like them that much. I get the eerie feeling sometimes that too many pictures, too many captured memories on film are kind of like a sort of karma working against me. Seems like the many glimpses we have into the past are slightly disturbing in some cases. Crime scene photos for instance. It is disturbing to have so many pictures of something horrible happening to someone. Why do we want to keep looking at that? I guess my view is kind of an aboriginal view, at least from what I understand. I feel like taking a picture takes something away from the person. Of course, I am part American Indian and Irish, so could be I am just extra superstitious........maybe...........
