How does Facebook Sharer select Images?
Ok, I just launched a site: http://www.haavekuva.fi/ yesterday and on that site I’ve implemented Facebook’s social plugin “fb:like”, so it’s possible to like a photo.
Everything else works fine (“Like” gets published to my feed with correct title, link, etc.), but for some reason the og:image does not show up? When I hover over the the”Like”-link (“Janne likes Shopping on Haavekuva.”) on my profile feed, on the hover-box it shows only Facebook question mark.
If I linter the page at developers.facebook.com/tools/lint/?url=http%3A%2F%2Fwww.haavekuva.fi%2Fkalenteri%2Fpaiva%2F2010-10-10%2Fshopping%2F there the photo is correctly visible.
Does anyone have any idea why so?
No image will be represented within the stream when a user “Likes” something, unless they also add a comment (at the point of liking it). Not sure if that was the answer you were looking for, but hopefully it clears things up.
