Facebook Share returning Blank Thumbnail was created by Goh Yew Hoe
I can't seems to get the thumbnail to display when I share my articles onto facebook. With the debugging tool, I see that facebook is able to find my image and it's url but it display it as a blank?
Here's the link to try it with an article from my site.
Facebook Debugger Tool
As you can see under object properties, for OG Image, the thumbnail is blank but if you click on it. It actually links to the image in my article. The large version of the image.
However I understand that in K2 parameters, there is a place to define image size to share to facebook. Looking at the scrap data from facebook, I can find that meta tag which I define as extra small.

Hi. It seems that Facebook did some changes and now it uses the open graph meta tag (<meta name="og:image" content="XXX" />) instead of the image tag. The best way to do this is find a plugin since Facebook requires also other open graph tags.

I have a plugin that handles the opengraph however it doesn't work very well for the image. The og image tag will only be detected properly if I insert the image into full text of the article thru the editor. It doesn't work if I just use the intro image given to K2.
This creates a redundant step and also causes problem if using simple image gallery pro plugin because it will just return transparent.gif as placeholder for the gallery. I think the reason why facebook returns with a blank thumbnail at times is also because its trying to download the _L large image size which then timeout in the process, I'm not sure.
I think the simpler way atm would be perhaps to modify K2 source so that instead of saying

Facebook requires much more tags than just the og:image. So adding just this is not a solution. URLs will still get errors by the Facebook debugger tools. That's why i suggested seperate plugin for this. You can however do this in your template overrides:
$document = JFactory::getDocument();
$facebookImage = 'image'.$this->params->get('facebookImage','Small');
if($this->item->$facebookImage){
$document->setMetaData('og:image',substr(JURI::root(),0,-1).str_replace(JURI::root(true),'',$this->item->$facebookImage));
}

I added the code you suggested to item.php with template overwrite and see this added attribute from the scrape url now.

After some very tedious Google search, I found an old topic that contains a solution code by one of the users here.
