Bad image size when opening details (portrait mode only)

[psion007]

Everything is in the title.

The image should (yes ?) fit width and it is not (see picture)

(Image fits well in landscape orientation)

I agree with psion007, the images should always be visible in full in the detail view, whatever the ratio, portrait or landscape.
It’s important when looking at very similar pictures, willing to select some or compare data.
IMO it should be same design as in the tools (edit, draw, crop,...) so an option doesn't seams necessary as this design allows to zoom (which is not the case in detail view right now)
