Make sure the web page you're developing isn't tested/located on a local server (like WAMP/MAMP etc.). Facebook might not necessarily get every property exactly right. Try testing it live.

Check your image size is at least 200x200 pixels (do not use a thumbnails). Then re-scrape your image with facebook's debugger tool
