IrfanView

Irfanview is maybe the most known picture viewer, and if it is that well-known is not a fact of luck, but because it offers really good options and features for free and because it is the fastest and easiest-to-use picture viewer we can find.

Irfanview supports the most important picture formats, including BMP, DIB, JPEG, GIF, animated GIF, PNG, PCX, multipage TIFF, TGA, and more.

In addition it supports drag and drop, viewing of full folders, TWAIN, automatic picture slide, format conversion and even you will be able to make some changes to the photographs or pictures like resize, blur, color, shadows,...

Now it includes more features and options, such as batch Auto adjust colors, enhance colors, or even an EXIF dialog button which lets you place pictures in Google Earth.
