I have a PHP application which has a Share on Facebook button that,On the development server shows the thumbnail images correctly and allows the user to select between themOn the live server, it does NOT show the thumbnail images at all.The relevant portion of the .htaccess file is:# Set up caching on media files for 2 days<FilesMatch \.(gif|jpg|jpeg|png|flv)$>ExpiresDefault A172800Header append Cache-Control public</FilesMatch>I'm using the exact same set of php files and .htaccess, but the server configuration is different.What could be causing this? Note that the text appears fine.Edit1We are also doing some URL rewriting related to images in the .htaccess (on both servers):...RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L]...RewriteRule ^.*/images/(.*)$ images/$1 [L]...Would that be somehow making a difference? Images appear fine all throughout the site.(I posted this question earlier as https://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images))
Share on Facebook does not show thumbnail images
php;htaccess;images;facebook
The reason why Facebook does not show the thumbnail is because it cannot fetch it. Why not try testing it once without the URL rewriting?
