Facebook. How to pull up pictures?

Question

Blogs

The question is the following. For example, I have a blog. I want to post a link to it on my Facebook wall, and as you know, it automatically pulls the title, announcement, and pictures from the page on the link. The problem is that all pictures are pulled up, including the design, except for the one posted in the post. What attributes are needed or is there some tricky format there?
