The best damn freeware graphics viewer around has been updated
Irfanview, the best freeware graphics viewer out there (in my opinion), has released version 3.8. If you have a file that's sitting on your hard drive and you know it's some sort of graphic (or even a video or audio file) just try opening it in this program. Based on the amount of file types this small download can open, you'll be hard pressed to find something it can't open. It'll even give custom icons depending on the file types. Remember to download the plugins as well for the program to enable more features.
I've been using this program since version 1.x and absolutely love it, and it's great for power users as well as simple tasks. Check it out! And don't forget the Irfanview Explorer Extension for more power as well.
