IrfanView										(pronounced EAR-fan-view)										is primarily a lightning-fast photo										viewer supporting virtually all image										formats. For more than a decade, it has										been dependable and free software										image viewer. Today, IrfanView is so										much more:
- Create Windows screensavers and											slideshows
- Advanced, automated image											conversion
- Photo transformation effects,											both built-in and through Adobe											Photoshop Plug-ins
- Cropping, resizing and simple image											editing
 
Lightweight, Fast Image Viewing
If you are frustrated by how long it									takes to bring up a photo on your PC,									IrfanView may be for you. It doesn't try to									jump through a lot of hoops to show you the									picture (unlike Windows XP). It displays your									photo almost as quickly as it can read it in.
Want to browse other photos in the										same set? Just use the space bar. Want										to see your picture full screen? Just										press the Enter key.
IrfanView's simplicity makes it										extremely effecient.
 
Create Portable Screensavers and										Slideshows
IrfanView has two ways to create a										single-file slideshow that you can take with										you. These slideshows are playable on										any Windows computer. You can even add										MP3s as background music.
The first type creates an										"executable" file. Just double-click the										file to play your slideshow. While its										playing, you can use the arrow keys to										move back or skip ahead in the										slideshow.
The second type of slideshow is a										Windows compatible screensaver. To										install the screensaver, right-click on										the file and select "Install" from the										menu. Your slideshow is now the default										screensaver!
 
Compatible with Every Image Format!
It's a bold declaration and it's very										close to the truth! If you have a										picture file that you can't seem to										open, IrfanView will probably display										it.
Not only does it open your standard										JPEG, GIF and BMP files, but it opens										images that Windows can't on its own. These include										Cannon Raw files (CRW and CR2),										Photoshop files (PSD), Icon files (ICO),										PaintShop Pro (PSP) and Kodak Photo CD (PCD). The IrfanView web site has a complete list of files it is										compatible with.
 
Some Features Require Learning Curve
IrfanView doesn't shy away from										technical terms, doesn't hide advanced										options and has accumulated a great										number of features over the years. As a										result, learning some of its features										can be intimidating.
The help is pretty good, though. And										I plan on writing some step-by-step										articles. If you're willing to spend										some time learning, you will really get										a lot out of IrfanView.
 
Modify One Image or a Batch of										Them
IrfanView gives you the ability to										crop, resize, apply effects and covert										to different file formats. Providing										these features in a free program is very										nice.
What's downright generous is										IrfanView's "batch processing" function,										which allows you to apply these features										to multiple pictures in one swoop. Just										give it a list of images, tell IrfanView										how you'd like to modify them (make them										smaller, for example) and off it goes. I										don't know of any other free Windows										program that offers this. 
 
Not Vulnerable to Photo Viruses
IrfanView uses its own algorithms to										display your photos. This code is fast										and is independent from similar code										built-in to Windows (called the Graphics										Device Interface or GDI).
In 2004 and 2005, viruses we're being transmitted										through JPG and WMF files that targeted										flaws in the Windows GDI. Since										IrfanView doesn't rely on the GDI, it is										and always was immune to image files										containing these viruses.
 
EBay and Google Plug-Ins Support										Author
When installing IrfanView, it gives										you the option to install the Google										toolbar and an E-Bay plug-in. These are										free, they are not spyware and										installing them rewards the author,										Irfan Skiljan. Unless you change the										default option, they will be installed.
