jpeg by default is a lossy format, i.e. everytime you open a jpeg file and
save it back you end up losing some quality. jpeglossless operations work
by not fully opening the jpeg file, but by modifying a few parameters in
the jpeg file (not entirely true, but this explanation will suffice).

now coming to your suggestion: it doesn't make sense to have dialogs for
jpeg lossless operations - rotation, black-white conversion, flipping; as
it should be quite obvious to user whats going to happen to the image, no
need for a preview or stuff like that. these operations are meant to be
quick access operations (very frequently used by digital camera owners)
and having a dialog will slow things down for them.
