Server Load?

I noticed that we still have fully working, visible screenshot posts dating back to 2003 on the forums. Wouldn't having this amount of images residing on a/some server(s) be detrimental in some way?
Along those lines, I'm wondering if this non-deletion policy is part of the reason for the 150kb limit on shots.
