The site where I use K2 has tons of photos on each page. So I figured out how to make sure that when someone shares one of my K2 Item pages on Facebook, it uses the Item Image as the thumbnail, instead of making the user scroll through a ton of pictures. So I thought I would share the info!Insert this code into /components/com_k2/views/item/view.html.php. I put it in the Metadata section.         if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.md5("Image".$item->id).'_XS.jpg')) {            $document->addCustomTag('<link rel="image_src" href="'.JURI::root().'media/k2/items/cache/'.md5("Image".$item->id).'_XS.jpg"');         }In order for this to work properly, your XS images must meet Facebook's thumbnail size requirements. developers.facebook.com/docs/share"The thumbnail's width AND height must be at least 50 pixels, and cannot exceed 130x110 pixels. The ratio of both height divided by width and
width divided by height (w/h, h/w) cannot exceed 3.0. For example, an
image of 126x39 pixels will not be displayed, as the ratio of width
divided by height is greater than 3.0 (126/39 = 3.23). Images will be
resized proportionally."

pfff that sux about the image size standards... pfff it SUX.. i really needed that option
thanks for your effort

i tired adding this just after the //set metadata and it's not working, it still loads all the images

Hmmm.... it works on my site. www.homewardtrails.org


How good is your level of knowledge of PHP? When you say "just after the //set metadata", you didn't put it on the same line as that and therefore comment it out, did you?

my php knowledge is low but ofc it was not on the same line .. ^^

any ideas?

Another thing that's probably obvious but worth checking... you're looking at a page that's an item view, right? This fix doesn't do anything for a page that shows a category view, tag view, etc.

Beyond that, all I can tell you is the process of elimination that I would use. First I would go to a K2 item view and see if the link rel=image_src tag is showing up in the head tag at all. If so, then there must be a problem with what's in the tag if it's not working so you need to mess around with that part of it. If not, then there must be a problem with the if statement or with the addCustomTag so you need to mess around with that... like maybe copying and pasting from the forum messed up a character or something.

Well actually i am not able to do this- i dont know php :(.. However i may tough of what could be problem.. in item view in my case, i am not displaying the thumbnail picture.. but only in categoryItemView (dose it have to be shown in item view as well?)
note: and yes we are talking about IN itemView

So just to make sure I'm understanding... You're on the item view of a K2 item that HAS an "item image" but the image isn't displayed. No, the fact that it isn't displayed shouldn't affect it. As long as the XS version of the image exists, it should work.

Did you check to see if the head tag of the page contained a link rel=image_src tag? Checking that doesn't require PHP knowledge.

Very nice code Kemler, it did exactly what I wanted to do. The only problem is that you forgot a to close the link tag and it was breaking my template. The correct code would be:
if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'cache'.DS.md5("Image".$item->id).'_XS.jpg')) {            $document->addCustomTag('<link rel="image_src" href="'.JURI::root().'media/k2/items/cache/'.md5("Image".$item->id).'_XS.jpg">');        

} I'm replying only because someone might find it useful in the future
