Image is partially downloading,

I cannot download the file in following url: http://ift.tt/1Hf92xf

Only a part of the file is being downloaded.

Following is my code. Please let me know if I'm doing anything wrong.

            URLConnection urlConn = new URL( "http://ift.tt/1Hf92xf").openConnection();
            InputStream is = urlConn.getInputStream();
            FileOutputStream fos = new FileOutputStream( file.getPath() );

            byte[] buffer = new byte[4096];
            int len;

            while( ( len = is.read( buffer ) ) > 0 )
            {
                fos.write( buffer, 0, len );
            }
