Looks like the question has already been answered here. Here is another useful link. Thanks for asking. It made me find out something I can use.

Update: After trying it and finding it not to work I tried the method in this post. It initially didn’t work, but that was because I forgot to upload the image. So it may be the case that the original method may still work. Here’s the template I used in my head section:

<meta property="og:title" content="your title">
<meta property="og:description" content="your description">
<meta property="og:image" content="http://www.yoursite.com/your-image.jpg">

Update 2: If it seems that Facebook isn’t recognizing your code, try their lint tool. This does two things. The obvious one is that it reports any errors in your code. The second is that it refreshes Facebook’s cache of the page. I had two pages where the new code wasn’t recognized until I did this.
