Panoramic photo

I want to add an panoramic photo between regular ones.
Because the width and height of the other ones are smaller,
the panoramic photo will have the same width.

If I set the width to an higher number, the other photo’s
( mainly the landscape oriented ) are getting stretched to match
the panoramic one.

Is there an option to exclude the panoramic photo from the
given values of width and height?

Or is this an option that will be added later on ?
