Comparing view of two, three, ... pictures

[Klsg]

This is i.e. provided in the faststone viewer.
I rate it very handy.
But it seems, that faststone is not very eager to implement a view of newer picture formats as heif, avif or jpeg xl.
Therefore I ask, whether irfan has planned similar.

br, kls

You may open multiple IrfanView windows at the same time.

You may open multiple IrfanView windows at the same time.

this is not, what I mean and not the same.
Pls have a look at the attaches pic, comparing two pictures; you may slide / merge one over the other and magnify and compare exactly.
