By default, Windows 7 and Vista open any GIF (.gif) images in Internet Explorer. This becomes quite problematic when we want to view many GIF images at one time.
How to open/view gif images with Windows Photo Viewer –
Just open the properties of any GIF image by right-clicking on it. Under properties, click Change. In the ‘Open with’ window, open Other Programs and select Windows Photo Viewer as the default program to open with. Now click OK and again OK.
That’s it. Now all your gif images will open in Windows default photo viewer.
