V2.5 : fix mime constant (deprecated)

This Fork is suitable for you if you want to share Guppy articles or news (only for the moment) on Facebook.
The aim is to introduce the meta tags required by the facebook Open Graph API in order to select what are the details to be shared
on a particular page :
title/ description / site name / picture …
These informations must appear in a meta tag with attribute property=“og:xxxx” in the tag.

Proposed mapping, for an Article or news :
og:site_name => the name of the site
og:url ==> url of article or news
og:type ==> article (constant)
og:title ==> The title of the Guppy article or news
og:image ==> First image in the page with alt field =“FB”
og:description == > First lines of the article or news + invitation to read the article or news on the site
og:locale ==> “fr_FR” or “en_US”
! take care for news to only display a single news before sharing on FB. !

2- open the file FB_og_meta.inc file
3- locate the line $FBdefault_image=“skins/skin01_LBN_2014/img/photo.jpg”; (should be line 72, the value here is an example)

In the Guppy “admin/structure/Social network code for the services” box, add the following code:

2- In your articles or news, you only have to select the picture you want to be displayed on Facebook as thumbnail for your share,
you do so by entering FB in the field “texte de remplacement”/“Replacement text”
That’s all, when clicking on the share button, your article or news should be given it’s true title, the url should be correct, and the description should be the beginning
of your article + “… read more …”""
Note, for the news, it will work only if you display a single news, not when displaying the list of the last news (just click on a title of news, then share it)
