Good to hear your smug, self-satisfaction is keeping you warm, but anyone who thinks this is comparable to the default image viewer in Windows (even windows 30+ years after IrfanView) is out of sync.
Literally everyone else in this thread said the exact same thing, they do not use it anymore because nobody needs it anymore.
Speaking of out of sync: Enjoy your self-satisfaction in using some ugly ass looking outdated software that has 100 functions you do not use.
