XnView Software

Is there away to set MINIMUM image size to scale?
Example:
I have a folder with images. Some of them has dimention 1920x1200 and it is normal to display, but some of them is images for the program. They are like icons 9x6, but XnViewMP displays them in full screen (1920x1200).

So I ask is there a setting to lock zoom for SMALL images?

It's not 'Fit for images, large only' that you would like?

Thank you!
I've found it here:
Settings -> View -> View -> Auto image size -> Fit image to window, large only
