FACEBOOK REQUIREMENTS FOR IMAGES
The image must be at least 50x50 px (though minimum 200x200 px and maximum 1500x1500 px is preferred) and have a maximum aspect ratio of 3:1. Maximum image size is 5MB. We support PNG, JPEG and GIF formats. Facebook scrapes your page every 24 hours to ensure the properties are up to date.
Something a correspondent said in a post pointed me here and I tripped over this great extension.
Problem now resolved! This plugin is the answer to my prayers!
I had one issue with W3 validation, but was able to solve it by editing the plugin's php file so that it places the image links in HTML comments . Facebook still reads the link, and the page now W3 validates :)
I wish all plugins were as easy to use and as functional as this one!
META tag with attribute PROPERTY is valid in HTML5 and this is required attribute by Facebook that it can not be changed to anything else.
