FastStone Image Viewer offers a nice modern interface and many very useful features in a compact freeware package. This program is similar to IrfanView, but does not support quite so many file formats.
FastStone Capture is one of the easiest to use screen capture programs, and is proving invaluable in capturing screen shots in .png format for this Wiki. However, it is not free.

There is also the free Microsoft Windows Snipping Tool, available from XP onwards, which is very easy to use.
