XnView Software

When opening a picture file that is smaller resolution than the screen there is no option to select default zoom mode to "Fit Image" ,Fit Width, Fit Height, or Actual Size then select Reduce or Enlarge so image always fits to screen.

Can this be added ?

Also when scrolling using the mouse wheel when you reach the last image can it scroll from the beginning ie wraps around ?

you have 'Fit image to window'

Hello!

I tried this function but it doesn't work. Window hasn't changed its size.

The View > Auto image size -- Fit image to window option fits the whole image to the existing window that is open:
The window that is open isn't resized, the image is displayed in the best fit to the existing window.

Normally either the image width or the image height will be fitted to the existing window dimensions, as it usually won't be possible to fit both.
