Problem: you share link with Joomla! article on Facebook and Facebook can not find correct image. HERE IS A SOLUTION: This plugin adds invisible Open Graph tags in HTML with image from your article, so that Facebook would know which image to display.
Images from Open Graph tags are also respected by Google+ and will be used when you click +1 button and share link on your profile.
– only one image is searched in article content
– works only with single article view
– select default image when no image was found in article
– adds Open Graph tags with image and page details
– debug mode which displays added Open Graph tags
To check which images are inside Article add at then end of page URL: &tmpl=component or ?tmpl=component.
Go to download page and try to share it on Facebook status or click Like button and Post to Facebook.
Joomla 1.5, 2.5, 3.x
This plugin is not a Like button and it does not display any share buttons.
It does not work with K2, Zoo.
FACEBOOK REQUIREMENTS FOR IMAGES
The image must be at least 50×50 px (though minimum 200×200 px and maximum 1500×1500 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.
