When I share articles from some websites, facebook asks to choose which image to use for article's thumbnail. This doesn't happen with default joomla articles unless you use a 'link rel' in the code.
Actually I'm using the same thumbnail for all articles by using this code:
Code:
<link rel="image_src" href="http://www.website.com/preview.jpg" />
inside <head> </head> in /joomla/templates/mytemplate/index.php
and it's working.
However the 'preview.jpg' is grabbed by facebook even though shared article has 2-3 images included.
Anyone knows how to let facebook grab images from shared articles and use them for the preview?
I've also had a look here:
Share | Facebook
and tried adding <link rel="image_src".... code directly in articles with no luck.
Thanks in advance.
