Conflict FB debug tells me og:image isn't defined - facebook

I have a xenforo forum that allows users to like or share pages to Facebook. I am having a problem getting og:image to be consistent. I have defined og:image yet there seems to be an inconsistency.
I am using the Facebook developer debug tool to scrape information from my site. The debugger shows the warning:"og:image could not be downloaded or is too small"
However, just a few lines below in the section titled: "Based on the raw tags, we constructed the following Open Graph properties" and it displays my og:image that is on my site.
Yet, when a user actually performs an organic share, no image is shared on Facebook. What should I fix? Thank you

Make sure the picture is accessible and you are using the correct size:
Use images that are at least 1200 x 630 pixels for the best display on high resolution devices. At the minimum, you should use images that are 600 x 315 pixels to display link page posts with larger images.
...
Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping.

Facebook preview image doesn't match scraper information

I just recently launched a game on steam, and when I share a link in facebook the preview image doesn't appear.
I ran the object debugger.
From the results, in the og:image field, I can see the image correctly, however in the preview itself the image is broken.
Any ideas?
Edit: Since this is a steam page, my ability to influence it is limited. I can only change some images, but I cannot add meta tags.
I did find, however, in this post, that a <link rel="image_src" href="/myimage.jpg"/> tag should also be identifiable by facebook as a preview image. For some reason in my page facebook either ignores this or treats the image as invalid (although it is larger than 200x200)
og:image could not be downloaded or is too small
og:image was not defined, could not be downloaded or was not big enough.
Please define a chosen image using the og:image metatag, and use an image
that's at least 200x200px and is accessible from Facebook.
'http://store.akamai.steamstatic.com/public/images/game/game_highlight_image_spacer.gif' will be used instead.
Consult http://developers.facebook.com/docs/sharing/webmasters/crawler for more troubleshooting tips.
So we do have the reason why it is blank (spacer.gif is blank)
This is the same for other pages as well...
http://cdn.akamai.steamstatic.com/steam/apps/455980/header.jpg?t=1459222551 <-- Can be found in the header...
So lets have a closer look at the image itself...
The images are creatd ondemand (so it seems) and you (a.jpg) is the same as Cities Skylines (b.jpg)
So no idea at all... Maybe a problem with Steam's CDN (FB is unable to find the image. Did you update the image recently?)
Sorry not to be able to help. The image itself cannot be faulty IMHO as stream is processing the image every time...
Cannot say more :/
When content is shared for the first time, the Facebook crawler will scrape and cache the metadata from the URL shared. The crawler has to see an image at least once before it can be rendered. This means that the first person who shares a piece of content won't see a rendered image:
Pre-cache the image with the URL Debugger
Run the URL through the URL debugger to pre-fetch metadata for the page. You should also do this if you update the image for a piece of content.
Use og:image:width and og:image:height Open Graph tags
Using these tags will specify the image to the crawler so that it can render it immediately without having to asynchronously.

og:image shows only after 4 share "clicks"

I've seen this is a common issue here on stack but it seems that the answer is always dependent on the specific scenario. I'm looking for a fellow coder to give me that "AHA" moment.
Problem: Ads posted to my website do not show the og:image content when shared to facebook until the ad is shared at least 4 times
I have thought about/ tried the following things
Checking the image size to make sure it's not large (128kb) is the norm. I compress all uploads.
Giving the ad some time to marinate before sharing (perhaps the fb crawler takes a while to cache the page)
I tried using the debug crawler tool on fb to see if I could reproduce the problem and I indeed could.
I tried sharing the ad to my own page regardless of the missing image to see if the image showed up on my wall. It did not.
The image will not show up on ANY shares until someone has clicked on the share icon on an ad at least 4 times. It seems to me like it might be some latency issue on facebook's part.
What could cause og:image to only show on subsequent share clicks?
Edit
Here's a test ad.

Reading https://developers.facebook.com/docs/sharing/best-practices I found this, which might be just what you're looking for:
Use og:image:width and og:image:height Open Graph tags
Using these tags will specify the image to the crawler so that it can render it immediately without having to asynchronously.
This means, if you set the width and height of your og:image with tags, the image will show straight away.
UPDATE
Actually debugging your URL shows like this URL is redirecting to another page, and then another. Which makes me suspect the Facebook crawler is not able to access the actual OG meta tags you're using.
As a random test, I would add OG metatags to that last URL and see if Facebook uses them. But the actual solution would be to use URLs which are actually reachable to FB (no credentials necessary).

Why suddenly minimum image size for og:image Facebook OG

The developer page of Facebook tells me:
If your image is smaller than 600 x 315 px, it will still display in
the link page post, but the size will be much smaller.
If I do this FB Debug Fetch my preferred og:image is not showing, Facebook tells me:
og:image was not defined, could not be downloaded or was not big
enough. Please define a chosen image using the og:image metatag, and
use an image that's at least 200x200px and is accessible from
Facebook.
QS1) Why is there now suddenly a minimum size required?
QS2) Why, if 200x200px is the minimum, is FB not having any trouble with my 140x140 image in this FB Debug Fetch? UPDATE: I just did the fetch again and now suddenly I get the same warning here, so I quess only QS1 remains > or is Facebook just corrupt and not always giving the correct information?

Primary images when Sharing page on Facebook

We have a PHP based real estate template and when we SHARE PAGE on Facebook, the resulting photos to choose from do not include the desired photo(s) to select from. IE we have 10-15 images on this page, and facebook only offers 3-4 as an option to share, none of which we want to share.
Suggestions?
Example http://kemptvillerealestate.com/listings/listing_body.php?id=118521
I have seen some cases that image size and/or aspect ratio did not satisfy Facebook's requirement and those images did not appear on users' wall, timeline or Facebook page.
The best practice is shown here and I think this is the latest one. As Facebook design including timeline, news feed and page changes this optimization practice changes accordingly. So be careful catching up the latest specifications.
So far the document describes as follows:
Use images that are at least 1200 x 630 pixels for the best display on high resolution devices. At the minimum, you should use images that are 600 x 315 pixels to display link page posts with larger images.
If your image is smaller than 600 x 315 px, it will still display in the link page post, but the size will be much smaller.
We've also redesigned link page posts so that the aspect ratio for images is the same across desktop and mobile News Feed. Try to keep your images as close to 1.91:1 aspect ratio as possible to display the full image in News Feed without any cropping.
And when you update images on your pages, make sure you visit Facebook Debugger and let Facebook crawler scrape your page again so they will get the latest version of your page content. Or you can do it programmatically as stated here:
This Graph API endpoint is simply a call to:
POST /?id={object-instance-id or object-url}&scrape=true
The response from this endpoint will be a JSON object that contains all the information about the object that was scraped (the same data returned when the Object ID is read from the Graph API).

No thumbnail shows on facebook, when I post a link to my site

I just published a new website. When someone tries to publish the link on Facebook, no thumbnail-options shows up, even though there are plenty of image-files to choose from.
When I post the link to the "gallery" section though, I get the option to choose a thumbnail from the images in the gallery only.
The url to the website: http://www.ridderhest.no
According to the debug tool: https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fwww.ridderhest.no the image is being detected correctly from your tags and it appears to meet the size requirements, does it work it you change the image to be slightly larger? the minimum supported size is 50x50 and that's exactly the size of the image, maybe a 51x51 image works?
