solved issue 166.

166) flickr: invalid/deleted picture url is redirected to https://s.yimg.com/pw/images/photo_unavailable.gif (width 500, height 374)
     javascript: img onerror event is never triggered for flickr pictures
                could error mark flickr images with width 500 and height 374 so that image is rechecked in util.missing_api_picture_urls
                there is no javascript solution for this problem. Most be a server request so that redirect can be traced
     rails:  util.missing_api_picture_urls: image_type = FastImage.type(api_gift.api_picture_url).to_s returns gif for deleted picture
             should make a special check for flickr pictures with width 500, height 374 and image type gif
             redirect and check final url
