Links to Photos on Old Blog Posts Keep Breaking

For the past week or so, I have had readers of my blog complaining to me that some of the photo links in my older blog posts have been broken; and when I go to the posts, indeed it is true.

I have no idea why this happened (though it is unacceptable); but I just spent the better part of two days going through all of the posts in question and painstakingly re-inserting EVERY photo; and the problem corrected.

Now, a day later, the complaints have started coming back in; and when I check again, the links are all broken again! In fact, even more of them than were broken before are broken now.

I can’t maintain a readership like this. Does anybody know how to correct this?

I am running WordPress Premium, which I renewed less than a week ago.

Here is a link to a post which will convey the problem:
