Google news results have an acompanying thumbnail next to articles that show up in the results.

If Google's crawler can't find a thumbnail to pull from our site, it uses its next best guess from another site, therefore linking the image to another site but still uses our headline.

Example: Headline from Reuters, Image from Livemint:

Our pages absolutely have images, they are not massive in file-size or dimensions, yet we are not having them pulled / crawled correctly. We have read up on the suggestions from Google, and from others around the web and nothing is panning out.

Has anyone had any experience where they can ensure Google news will pull a thumbnail of our choosing?
