Hello there
I have exactly the same problem. When i update one gallery, the thumbnails of the old pictures of this gallery, have a wrong size. In other cases, its not necessary to update a gallery to find this problem with thumbnails.
I know that i can fix the problem with hand, updating each time the thumbnails of each gallery, but i have more than 800 different galleries, i dont think that this can be a solution (update 800 galleries can be a little crazy) :(.
Thanks in advance for the help!
