Following changes have been made:
1. The OpenImage() function now checks if the image returned by the
mp3 and flac parsers is the default image if it is true then it
will query the lastfm api for cover image if no error is
received then the path to that downloaded image is passed else
the path is unchanged ( that is it will be the default image )
