The options for the saving of transformed JPEG images should be in "General > Read/Write > JPEG > Transformation" and look as follows (default):

Code: Select all

Method for JPEG transformations (rotate/flip):
(*) Only change existing or add new EXIF orientation tag
( ) JPEG block transformation
      If not all JPEG blocks are transformable:
      ( ) Allow cropping of up to 15 pixels at the right and/or 
          lower border of the original image
      ( ) Keep all pixels of the original image
      ( ) Only change existing or add new EXIF orientation tag
      ( ) Perform a lossy rotation with recompressing the image
      (*) Ask user what to do
[X] Set EXIF orientation tag to "1" after JPEG block transformation  
[X] Create backup file
[ ] Keep original file modification date/time
I support this request! Great idea/solution, Karl :D
