Thumbnail in facebook share

Tue, 14 Sep 2010 17:57:38 +0100

If you want to control the thumbnail facebook share displays you have to put somthing like that in header.tpl

Do not put this line if you want facebook to scan your site and pick up the first images.
If your logo is too large, you can always use a div with display:none of a smaller logo at the top of the body to have the image included in the facebook thumbnail

#Redirect forever
RewriteRule ^en/index.asp http://my.site.com/Home [R=301,L]
RewriteRule ^en/?$ [R=301,L]

Seems that the http is necessary for a permanent redirect
If you want also to overwrite directories, you have to put in tiki.tpl a base href
