Ok, I understand.
In my case, all my images started by two numbers and a letter (ex: 14F = June 2014). This way I can easily find my new uploaded images within the album.
So, as I can read in your post, there is no way I can fix it to Display images by: Filename ?
In my case, if I set it up to ... images by Filename.
It works ok, but when I do it again to another album (within the same session) it always returns to by ... ID.
Thanks
