facebook

When posting a website link in a Facebook wall post, Facebook fetches some content (title, text and image) from the website to show it to readers. Is there a way I can adjust / propose which content is used / preferred by Facebook?

enter image description here

I found someone saying to use <meta property="og:image" content="image.jpg">, but this doesn't seem to have any effect. But maybe Facebook caches these results for a while?
