I'm now facing down doing the same exact task for the third time (thanks to HP, and their seemingly inexhaustible ability to churn out defective laptops)..
I have approximately 150,000 photos that I've taken in the past 10 years. I've gone through them to pick the "good ones" twice... but lost that work twice with dead HP laptops.
This time, I want to embed IPTC, EXIF, or XMP metadata in the image files themselves, so that I CAN'T lose my work again.
I currently use ThumbsPlus 7.0 from Cerious... but it seems to lack the ability to sync keywords back out metadata in the image files.
What would it cost to get this feature added to ThumbsPlus? What are the alternatives?
PS: This is kinda what I expect Doc Searls to do as an experment in VRM land.
