Display All Image Formats with FastStone Image Viewer

January 31, 2008 – 12:45 pm

Previously, I’ve been using IrfanView to view all my JPEG formatted photos for quite a long time without bothering to use any other photo editing software. Everything changes when I first picked up my first Nikon digital SLR, snapped a few photos, copied all the images to my computer and suddenly realized that the photo format is in NEF format! And it was only then that I realized that my old, reliable, lightweight IrfanView does not support NEF (Nikon’s RAW image extension).

Not to waste any time, I googled the Internet for the ultimate photo editing software / photo viewer that can read and display all image formats, and I wonder if there is any. After some intense downloading and trying out a few programs, I fell in love with one – FastStone Image Viewer.


One thing that I love about FastStone Image Viewer is that it does not only function as an image viewer. This free software can do image conversion and image editing too! Oh my, that is already 3-in-1!
