I just installed this plugin because I was tired of Facebook pulling in random images from the website when grabbing a post. We use the NextScripts Social Networks Auto-Poster (SNAP) plugin to send posts to Facebook. That's been working great for the past 1-2 years, and now that I've installed the WP Facebook Open Graph Protocol plugin, the posts that contain an image are not being sent to Facebook. The ones with no image in the post are going out just fine, with the thumbnail image I specified in the plugin settings. Any idea why this would be happening?
