Hi, facebook not scrape image when the topic is shared by user via the share link below post, even though its successfully scrape by facebook debugger. Not sure weather its a bug or not.

What I found is that Facebook tends to give up if your image is: too slow too big too small When that happens, a second try on Facebook debugger works just fine. What solved that was using a CDN or a faster hosting.

Would it possible for us to actually set the og:image as the first image in the first message of the topic, if there is one? I think this would be a nice feature for social sharing, as opposed to letting FB try to scrape the entire page

That’s already the way it works. Make sure the first image in the post or topic (whatever you are linking to) is sufficiently large, and that’ll be the one used.

Obviously, much bigger things to address, but I would say that the image from the first message of the topic would be bette…

That’s the challenge of infinite scrolling though, right? If you’re looking at a specific reply in a topic and share, would you prefer it default to the first post, or the one you’re looking at? With some topics ending up thousands of posts in length it’s typical that the thing you want to share is…

Not thinking techincally, I would expect that a user who sees a good topic, may easily be seeing the first responses when they decide to share On very long topics, I could see some users wanting to share a specific reply, but I would expect this to be an edge case which could be handled by a small …

Not sure if this merits creating a separate topic, but has there ever been a thought of setting up a field for og:image that could be used for categories and the community as a whole? I typically want to invite people on Facebook and promote for users to participate in a specific category, but the g…
