 * Ciao,
    I have noted that, after having already added some thumbnails to my posts,
   if I change thumbnail sizes in Settings » Media (or I add new thumbnail sizes
   in functions.php) the new files for the new thumbnails sizes are not created (
   crunched). Actually it seems that the only solution to update thumbnail files,
   crunching the new ones, is to delete the image from the media and to reload it…
   a long procedure if you have already uploaded a lot of files. What about adding:
   1. an “Update all thumbnail sizes (re-crunch)” in Media Library; 2. an “Update
   thumbnail sizes (re-crunch)”: 2.1. to group actions selector in Media Library,
   2.2. near to “Update media” button in Media » Edit Media and 2.3. near to “Update
   image” button in Edit Post » Gallery ? Thank you very much
