Links to older blog posts not working!

I’m trying to show a prospective client a wedding I posted on 9/6/12, and the link is not working. I went in to check, and none of the links to prior/older posts is working. One or two photos show up, but mostly there are blanks or question marks where the photos should be. The photos are in my media library and show up when I go in to view the actual post on my dashboard, but anyone trying to access these older posts are getting these blank pages.

Can anyone help me with this?
