How do I get the correct picture to show up in the SERPs?

[network_operations]

When I search for "Popular Baby Names" using Google UK, I get the image below that is clearly displaying the wrong picture. I believe they are coming from a module on the page in the left rail. I know I can use Robots.txt to have Google not show the image at all, but I don't want to impact my click through. What is the best way to have the search engine either not display an image that is not part of the resulting article or better yet, pick the right image.
