This one is expensive, and also very detailed and advanced. If you're just looking to keep your digital photo files organized, even at a fairly detailed level, then ACDSee or Zoner will do fine for you.
I purchased IDImager Pro 2 years ago - $139!! (Though I did get a "competitive upgrade discount of $20). Never could get it working right on my PC. It was extremely slow while it tried desperately to create a catalog of my images, and certain views could not be rendered at all. It would lock up my machine if I went into certain views. Wasn’t a bum PC, or that old. I had a Falcon NW Mach V from 2006 and it was pretty powerful. So I don’t think it was the PC that couldn't run the program. More likely that IDImager didn't get along well with either the Athlon processor or - more likely yet - the Nvidia GeForce 8000 GT graphics card. (That Nvidia card caused a lot of issues with several programs; never did get drivers that were decent for that card).
But my problems running the program aside, I discovered that I really do not need that powerful of a program to catalog and categorize/organize my photos! It was way
over what I really needed! But ACDSee didn't have a program working well on Windows 7 at that time - I had their latest at the time - ACDSee Photo Manager 2009 AND ACDSee Pro Photo 1 - and believe it or not ACD Systems never accounted for Libraries in Windows 7! So when it looked for hard-coded file locations and ran into the libraries it froze. They didn't fix that until their next versions. In the meantime I purchased Zoner Studio and while that was usable it lacked some of my favorite features from ACDSee, so I kept looking for a better mousetrap to organize my ~20,000 photos. I broke down and bought IDImager Pro, thinking I would really, really organize the heck out of these photos! Turned out to be double-trouble for me. Whereas ACDSee catalogs my entire library of images in a very short time, IDImager does it in such a different, convoluted manner that it takes several days to catalog! I inquired about this on their forum and all there felt that was perfectly reasonable.
So now I am back to ACDSee Pro. Swore I'd never buy from them again after they let me upgrade to a product that wasn’t working on the latest Windows OS, but after trying all else I ended up back with them. As a company they pretty much suck at times, but their photo organization software is both reasonably priced and works just the way I need for it to.
OK, all that jazz just to basically say: Determine exactly what you really want to do with your photo collection before buying DAM software - Digital Asset Management - which is what IDImager actually is. It isn't what most amateur/hobbyist photographers need.
Sorry for the long post...
