Looking for some simple FREE applications to view, organise, edit, convert images/photos in Windows? There are literally TONS of applications for this. Although I tend to do all my media manipulation on Macs, there are times when Windows is all that is available. That said, here are my picks which are totally free & reliable for use in Windows.
First a classic, IrfanView. Irfanview supports MANY file formats. Great for batch conversions, cut/crop/resize, thumbnail preview/organization and more.
Next is XnView. A utility for viewing and converting graphic files, much like IrfanView. It supports over 400 file formats, batch resize, rotate, crop, color adjustments, batch renaming, and more.
Finally, and this one is more photography oriented. Google offers it's free software called Picasa. Organize and edit your digital photos. Additionally you can create online albums to share. If you like Picasa, you will be pleased to learn that it's also available for Mac and Linux.
