  • In the end I managed to solve this bug.
    It was easier than I expected, and, as usual in these situations, you always look for the most difficult solutions forgetting the easiest one back.

    For some mysterious reason it seems that OGP only likes thumbnails which dimensions are the same or more than 200 pixels. The fact is that when you upload an image on WordPress and set it as thumbnail, it will be resized to, by WP defaults, 150×150 pixels.

    In my case, the easiest solution was running the Facebook debugger which in turn gave me the ultimate hint on what I was lacking.
    Actually (forgive my hilarious madness) I was definitely lacking in size.

    After running a scan, I got this message:

    Open Graph Warnings That Should Be Fixed

    Small og:image: All the images referenced by og:image should be at least 200px in both dimensions. Please check all the images with tag og:image in the given url and ensure that it meets the recommended specification.

    So I manually enlarged a random thumbnail of one of my previous posts to the actual 200×200 pixel size and tadadah!!! Size DOES matter!

    Facebook now shares the proper link and proper image also from WP homepage or single post without hacking any code. Hope this can be of any help to everybody has the same issue!

    Since the total lack of help/support I’ve fixed things by myself in the end.
    It seems that OGP only likes thumbnails which dimensions are the same or more than 200px. If you upload an image and set it as thumbnail (which dimensions are, by WP default, 150×150 pixels) you’re going to get an error message if you run your post’s link into the FB debugger like this:

    I’m sorry, perhaps I’ve not been clear enough on my details explanation: you are allowed to choose what pic to use on sharing ONLY when you copy/paste the link of your article on Facebook page, but when you click on “Like” from your homepage (mine is this) or from each single post, Facebook scans and decides by itself, showing ONLY one of the images from CRP plugin.

    What I’m looking for is a way to force OGM to select images not coming from CRP plugin when clicking on “Like” in the above mentioned conditions.

    That’s it, if anybody found a way, I’d be very pleased to know HOW..

    Thanks zep, I’ve tried also this way, but not luck at all 🙁

    Hi Niall I’ve been silently following this thread ‘cuz I have the same issue as zep101.
    I’ve placed had a filter, as u showed in the example, in my funtions.php file and I’ve set a “featured image” on one post to check if anything was changing with a negative feedback.

    I definitely can NOT force Facebook to choose the “featured image” thumbnail instead of the others shown in each post, very frustrating indeed!

    I overwrote it directly on the parent theme and now it works, but yet I don’t understand why it wasn’t working before.

    Now I have another issue: since I’m using also the Contextual Related Posts plugin (http://ajaydsouza.com/wordpress/plugins/contextual-related-posts/) which places thumbnails of related articles at the bottom of my own, when I hit Like/Send button, Facebook plugin does not grab the right thumbnail for the link to be sent, but it chooses randomly between one of the five (the one of the main articles plus the four of the linked articles).

    Any idea on how fixing this annoying issue as well?

    Thanks for your reply: I tried both the solutions, but none of them gave me back any result 🙁
