IrfanView is a very fast, small, compact and innovative FREEWARE (for non-commercial use) graphic viewer for Windows 9x/ME/NT/2000/XP/2003/Vista.
It is trying to be simple for beginners and powerful for professionals.
IrfanView is trying to create new and/or interesting features in its own way, unlike some other graphic viewers, whose whole "creativity" is based on feature cloning, stealing of ideas and whole dialogs from ACDSee and/or IrfanView!
New PlugIn: Paint (Edit menu, Hotkey: F12, thanks to Matteo Italia!) It allows IrfanView to paint lines, circles, arrows, straighten image etc.
Support for embedded color profiles in JPG/TIF (Properties->Viewing) LCMS PlugIn, thanks to Marti Maria
New command line option: /advancedbatch (Apply advanced batch options to image) Allows many image operations, add text etc.
Lossless JPG Crop added (Menu: Options or Thumbnails (batch mode))
Added option to tag/mark files during browsing (window or fullscreen mode): Hotkeys: X = tag file, SHIFT+X = untag file, SHIFT+Q: show tagged files in Thumbnails
Support for FLV format (Flash PlugIn, thanks to Remio)
