The winning image-editing application is ...

IrfanView.

Between the application itself and its plugins, it's light as can be but does absolutely everything I need.

It took me awhile to figure out how to crop a photo to exact dimensions and get control over that process, but I did figure out that final missing piece of the puzzle.

OK, there were two missing pieces. I couldn't figure out how to create an image file, but now that I've crossed that bridge, I'm ready to say that Irfanview is the best shareware/freeware image-editor out there. I say "shareware/freeware," because developer Irfan Skiljan says the program is free for home or noncommercial use but requests a $12 or 10-euro donation for business use.

While I prefer remaining in the world of free, open-source software, a $12 shareware, closed-source program is way better than a many-hundreds-of-dollars closed-source program like Photoshop.

And the great thing about IrfanView is that it loads in a couple seconds. Try that with Photoshop.

Now if only Irfanview was available for Linux and Mac. That would be great. As it is, I will try running IrfanView with WINE (the Windows emulator) in Linux, and I will report back.

Along the way, I tried out MANY applications. I still love MtPaint, the best lightweight image editor for Linux, but it doesn't handle the IPTC info that I need to preserve. I'll have to check whether it destroys it, as the GIMP so tragically does whenever a JPG is saved.

Others I tried included the KDE apps Krita (love it ... but it doesn't do IPTC; again, I'll have to check what it does to existing data) and digiKam.

The latter -- digiKam -- is digital-camera interface software for the KDE Linux/BSD desktop. Soon KDE is coming to a Windows machine near you, and I predict that MANY Windows users will adopt KDE as their user environment of choice.

Anyway, digiKam does have an editing function, and it does support IPTC, though to the extent that IrfanView does. The problems: digiKam wants to create its own directories (like iPhoto) that seem to mandate multiple copies of the same images in hard-to-navigate-to places. And the act of resizing a photo can, for some reason, take many minutes and/or crash the app. If only the KDE people would put full IPTC editing capability into Krita, which I think is a great image editor. Fix that and fix the initial-open-quote problem in KWord, and I'd be a die-hard KDE user.

But again, IrfanView is -- in my opinion -- the best photo-editing program for Windows that's out there today.

Update: I didn't realize that my version of IrfanView was old. I'm using Version 3.95, and the latest is 4.10. I'm downloading the new app and plugins now. I will report later on how it works.

Another update: This guy installed IrfanView in Linux with WINE. And so did this guy. And this guy, too.

This, however, I don't understand at all, but it might help. Also, check out this thread.

Even further update: The IrfanView forum.
