According to Facebook's own documentation this is a known problem. The preview image isn't displayed until the Facebook crawler sees it, so the first person to share a page may not see a preview.
So, there is can be only 1 solution: after you have added new image, click on Facebook share icon and close share dialog (don't share). Then click one more time and you will see image. this steps you will need to do for all images.
