 Hi, im working on allowing image editor for PDF thumnbails
 https://core.trac.wordpress.org/ticket/62712.

 in functiion stream_preview_image() in wp-admin/includes/image-edit.php -
 line 766
 is function with filter
 {{{#!php
 <?php
 _load_image_to_edit_path( $post_id )
 }}}

 we can change filepath, but for example if we change to
 {{{
 metadata['sizes']['full']
 }}}
 which has mimetype image/jpg, function stream_preview_image() dont send
 image to browser. Bug is in

 {{{#!php
 <?php
 return wp_stream_image( $img, $post->post_mime_type, $post_id );
 }}}
 should be
 {{{#!php
 <?php
 return wp_stream_image( $img, $img['mime-type'], $attachment_id );
 }}}
