Choosing the thumbnail image that shows up on Facebook

Facebook "like", "share" or "send" buttons are a nice way to let your visitors share content from your website.

When I put a Facebook button on my site I noticed that it generated a thumbnail next to the shared content. Most of the time this thumbnail was a random image from the page that didn't correlate with the shared content. It turns out you can specify what image you would like Facebook to display with a meta tag in your page:

<meta property="og:image" content="url to image" />

Replace "url to image" up there with your image path and you're good to go. If you don't have this code, Facebook will automatically choose an image from your page.
