IrfanView is a compact, easy to use image viewer. More than that, you can also edit images directly in IrfanView, to produce a variety of effects. IrfanView was created by Irfan Skiljan.
Open IrfanView by clicking its icon on the Windows Start Menu or double clicking the icon on your desktop.
Click on the File Menu, then the Open option to get a file for use in the viewer. A dialog box will allow you to select the file you want. Click the Preview active box in the Open dialog to see small versions of images before opening them.
With an image in the viewer, you can manipulate it in a large number of ways. Most functions for changing an image are in the Edit and Image menus.
