 /* Because some f*cking services like flickr require an extra HTTP request to get the thumbnail URL,
    I have deported the thumbnail URL code generation here, otherwise this would slow down page generation.
    The following function takes the URL a link (e.g. a flickr page) and return the proper thumbnail.
