IrfanView sucks

You're probably wondering, why the harsh title? Well, the program itself might not be so bad, and above all, it's free. I've been using it for a long time. IrfanView resized picture quality, however, is simply terrible no matter what settings I use. I got much better results when using other software to resize pictures or photos.

A good alternative is XnView - like IrfanView, it's a free multimedia viewer, and it allows you to view no less than 400 hundred graphics file types!
