Picaview

PicaView is an add-on for the Windows Explorer shortcut menu.

With PicaView installed on your PC, right-clicking on an image file will not just display the standard shortcut menu but also a preview of the photo (with its dimensions and file format) and a series of new options.

PicaView supports the most common image file formats, like BMP, GIF, JPG, PCD, PCX, PNG, SGI, TGA, TIF, etc.

But PicaView is not just an image previewer. It also has other features, some of which can be really useful, especially considering how easily and quickly you can access them. The program allows you to configure and print images, set desktop wallpapers, convert image formats, and more.
