I have recently built a blog that is working well. However when someone tries to share the link on Facebook, the thumbnails of the images in the blog does not show up in the Facebook post box.
After doing some research i figured out that i have to create the following meta tag in my <head> tag ...... < link rel="image_src" href="http://www.example.com" /> that is supposed to list all the images that i have on the page so that the person that wants to share the page can have a selection of thumbnails to choose from when sharing the link.
I assume that i have to replace the href with the url to images on my page using the <% control %> feature, but i am unsure if i must use $url or $image or $file????? I have attached a screenshot.
Some help would be appreciated
