Og:image Width and Height was created by mjmartino

Hi Fortis
Could you add in new version meta tag og:image
Meta Tag <meta property="og:image:width" content="1200" />
Meta Tag <meta property="og:image:height" content="600" />
If facebook not found this tag og:image with width and height image is not grab the first time. The workaround is to add the link a second time, then FB downloads the image, but it is annoying.

Regards :)

I'm not aware of such an issue (and we deal with large news sites daily - so I'd know for sure).

Plus, to add automatic width/height values means PHP would work to read an image's dimensions using GD, which is wasted CPU resources really...

In any case, it's easy for you to override any K2 meta tag directly from your K2 template overrides. Inside your item.php override, add this at the top of the file (after <?php):

<?php

// no direct access
defined('_JEXEC') or die;

// Get the image and its dimensions
if($this->item->params->get('itemImage') && !empty($this->item->image) {

    $basename = basename($this->item->image);
    if (strpos($basename, '?t=')!==false) {
        $tmpBasename = explode('?t=', $basename);
        $basenameWithNoTimestamp = $tmpBasename[0];
    } else {
        $basenameWithNoTimestamp = $basename;
    }

    $imagePathOnSystem = JPATH_SITE.'/media/k2/items/cache/'.$basenameWithNoTimestamp;

    if (JFile::exists($imagePathOnSystem)) {
        list($width, $height) = getimagesize($imagePathOnSystem);

        $document = JFactory::getDocument();
        $document->setMetaData('og:image:width', $width);
        $document->setMetaData('og:image:height', $height);
    }
}

Easy-peasy with K2 :)

Change to:

<?php

// no direct access
defined('_JEXEC') or die;

// Get the image and its dimensions
if($this->item->params->get('itemImage') && !empty($this->item->image)) {

    $basename = basename($this->item->image);
    if (strpos($basename, '?t=')!==false) {
        $tmpBasename = explode('?t=', $basename);
        $basenameWithNoTimestamp = $tmpBasename[0];
    } else {
        $basenameWithNoTimestamp = $basename;
    }

    $imagePathOnSystem = JPATH_SITE.'/media/k2/items/cache/'.$basenameWithNoTimestamp;

    if (JFile::exists($imagePathOnSystem)) {
        list($width, $height) = getimagesize($imagePathOnSystem);

        $document = JFactory::getDocument();
        $document->setMetaData('og:image:width', $width);
        $document->setMetaData('og:image:height', $height);
    }
}
