I created this page to have a place to save my copy of IrfanView.

I have to say that the author has made his download so complicated (at least last time I tried it was deadly complex!) that I have to just keep my own copy somewhere. Maybe it's illegal, but the software is freeware anyway.

You can find the original (and most certainly more advanced version) on his website: http://www.irfanview.com

There other tools one can use to work on images as follow:
