Comment:

 I really wish this will be fixed!! This is really sad that WP lost the
 transparency in the PNG... Why can't it be integrated into WP main code?
 I have to do and redo the modification at each update!! :-(

 After the line 2294 of this file:
 http://trac.wordpress.org/browser/tags/2.2.1/wp-admin/admin-functions.php
 add the following lines:
                         if ( ( $type[2] == 3) AND ( function_exists(
 'imagesavealpha' ) ) ) {
                                 imagesavealpha( $thumbnail, TRUE );
                                 $trans_colour =
 imagecolorallocatealpha($thumbnail, 0, 0, 0, 127);
                                 imagefill($thumbnail, 0, 0,
 $trans_colour);
                         }
 This code was taken from this documentation page:
