In this post I see 3 images. http://lorencereport.wordpress.com/2007/10/25/movie-review-my-kid-could-paint-that/
The first and last are very close to the text and the middle on is not. I would -> Manage -> Posts and locate the post and click “edit”. Once in the editor I would switch to “code” and examine the differences between the codes of the first and last images and the middle one. Then I would make the appropriate code change required so all the images display like the middle one does.
