Requested Fit large image side to small screen side

[Konstantin]

When viewing a series of pictures, the landscape images appear much larger than the portrait ones. This happens both with the "Fit to screen: large images only (recommended)" display setting, and with all the other options except those that either crop or deform the image. I find this behavior so distracting that I tend to avoid altogether taking portrait oriented photos. A solution to this problem would be to add an option to fit the large image side to the short display side and keep this setting irrespective of the picture orientation.

I propose that you resize the Irfanview window to a square with sides equal to the short side of the screen. Then choose "Fit large images to window"

Thank you Jazzman. The problem with your solution is that you don't get the fullscreen effect: the window borders, toolbar, etc. remain visible. This is distracting and also reduces the final size of the image.

... fullscreen effect ...

Ahhh, but you hadn't mentioned fullscreen

... the window borders, toolbar, etc. remain visible. ...

Some duct tape should take care of that ...

Seriously though, I see your point, for example when someone would want to project the images on a wall for presentation.

Don't give up shooting portrait format though, that would cramp your creativity.

Yes Jazzman, that's exactly the idea: a plain black screen and a sequence of portrait or landscape images all with the same size.

You could browse in slideshow mode where you can set up the sort of display you want.

Set up the slideshow dialog first with "Play in window mode" set to a square window. Set whether you want Automatic or Random order with Timer On or Off. (Example below)
Don't worry what images are set up to display as a slideshow in that dialog, you won't be using those.
Hint: For quick access to slideshow dialog press "W" to open, and "Esc" when you have set up and want to close. You do not need to Save the changes.

Load whatever content you want to display in the normal browse window, then press "Ctrl+W" to show them in slideshow mode. If you are not already in "Fit to window" press "3". You can press Enter to go back to the normal browser whenever you want. It will display a blank screen on exit from slideshow mode but just press the forward or back keyboard arrow to return to your original content.
Press Ctrl+W again to return to Slideshow mode. If you checked the "Remember file index on exit" box in the dialog (as example) then the show will resume where you left off.

Thank you Bhikkhu, this is a big improvement. However, I still do not seem to get the fullscreen effect: outside the black square window I get either the desktop or the last used program.

Thank you Mij, this is quite elaborate but leads to the same result as with Bikkhu suggestion with the advantage that the settings remain stored. Sadly, the fullscreen effect is also lost since the desktop or any used program appears outside the window instead of a plain black screen. Also, the setting is hardwired to the screen resolution so that it is useless if I switch to an external monitor.

OK. I understand what you are asking for now.
Are all your images the same size, just different orientation?
If so you could use Lock zoom. Set "Fit to screen: Large images only" or "Fit to screen: All images" for your Fullscreen option.
The landscape images are going to be bigger than you want initially, but when you get to the first portrait one press Shift+L to lock the zoom ratio. The rest of your show should then appear as you want it.
If you prefer a small top and bottom border for the portrait images too you could set the Display multiplier to somewhere around 95% for both height and width. Gives a nicer appearance IMHO if that is what you are after.

If that is not good enough you are free to request it from Irfan Skiljan yourself. He is usually more easily persuaded if you have support from other users though.
Speaking for myself I would not want to support yet another variant of Fit to Window - I think there are too many already.
What I would support though, especially for fullscreen, is the ability to set the maximum zoom ratio for the "Fit to screen: large images only" option. The existing option is equivalent to setting a maximum zoom of 100%, so that would be the default, but you could set it to a lower value to keep both landscape and portrait images the same size. I am more interested in being able to set it to 150% or so when I have small images from the net included in the show because I normally find it acceptable to magnify a bit above the present 100% limit.

Thank you very much Mij for your time and the proposed solution. The lock zoom method does exactly what I wanted after the first portrait image and as long as all the images are the same size. But that is a small price to pay since I seldom crop my pictures.
I personally think that having the requested feature added to the program would be even better, since many people might start using it as their default setting, but I might be wrong.
