Irfanview is another one of those cool program that does everything it needs to do and then more. Best of all, it’s free!
Irfanview started as a graphic image viewer but has now become more than that. It can do simple image manipulations like resizing, changing format, applying effects and screen capture (screenshots on this site are captured with Irfanview). With plugins it can even play media files like mp3 and avi.

Irfanview isn’t open source. It is freeware for non-commercial use and for commercial user the registration/donation fee is US$12 or Euro 10.
So far in my search, I have yet to find any open source or free alternative with capabilities anywhere near irfanview. So I am recommending it in their absence. Please leave a comment if you know of any alternatives.
Ifranview is an excellent graphical tool to have on every desktop.
