Free software is one thing, but if it doesn't serve a useful purpose, what's the point?
IrfanView is both, it's free and it's extremely useful.
To say IrfanView is a "Windows graphic viewer" is a true statement, but it barely scratches the surface of its capabilities. It does so much more:
• Create slideshows
• Lossless JPG rotation & Cropping
• Tag images for future editing
• Open images directly into your image editing software
• Batch processing (rename, resize)
• Create panoramic images
• Email images directly from IrfanView
• The only image viewer I know of that shows you the histogram
• It allows you do basic editing (like black & white conversion)
• soooo much more...
And with the latest version you can now browse your RAW files Too!
If you download it and don't like it or find it all that useful (not only will I will be stunned), I will give you back every single penny you paid for it! ;)
