For some strange reason... when you said to your script that select an image if didn't find the album art and the windows of select the file pops up... the .jpg can not be seing
! (I don't try it with other extensions) but when you copy the exact path like
"C:\Documents and Settings\All Users\Documentos\My Shared Folder 3\Rakim y Ken-Y\Masterpiece World Tour\soldout_cd.jpg" then your script displays the album art perfect...
