Facebook Posts

When an article is published on our blog at AzusaPD.org, we have it autopost to Facebook. Please look at the attached photo of what the post looks like on Facebook. You will see that the title of the article is auto-embedded into the Facebook comment section. How do I keep that from happening, so that you simply see the image and the link. Also, how do I get the square icon image on Facebook to be a full sized image, like when I copy the URL and paste it into a Facebook post. Somewhere, Easyblog is telling Facebook to show a small square image. How do I fix this as well. Thank you.
