:styles => {
:medium => ["654x5000000>", :jpg],
:small => ["260x50000000>", :jpg],
:thumb => ["75x75#", :jpg],
:facebook_meta_tag =>["200x200#", :jpg]
},
:convert_options => {
:medium => "-quality 80 -interlace Plane",
:small => "-quality 80 -interlace Plane",

},
:s3_headers => { 'Cache-Control' => 'max-age=315576000', 'Expires' => 10.years.from_now.httpdate }
}.merge(PAPERCLIP_STORAGE_OPTIONS)
