One of my favourite image viewer and minor editing is Irfanview (pronounced Earfanview). It is free for non-commercial use. The latest version irfanView 4.00 was released on the 23rd last month.
Here are some of the improvements:
- Improved Vista compatibility
- New display option: Center image in window (Menu: View->Display options)
- Toolbar skin option added (Properties->Toolbar)
- New Properties->Video option: Use DirectShow for playing (good for MJPG AVIs)
- New advanced batch option: Auto adjust colors
- New EXIF dialog button: Show in Google Earth (if GPS data available)
- The EXIF dialog can stay displayed on screen
- Several new plugIns are changed/updated.
- The bug fixes: Start folder, RLE BMPs and ANI loading
