You'll probably have to become a millionaire.
If you use a different imaging package - Macrium, Ghost, etc - you can just name the image as you like with something descriptive. That's what I do. But I normally only use the date in the name.
With the Win 7 incrementals, I would keep a simple text file noting the date the image was taken, and why. The text file is included in data backups. I keep a text file for notes about my imaging, but it's main use is to remind me what to rebuild before taking my next image. My process is to always restore my last image, look at my notes for any changes I want (a new useful app for example,) then make those changes, do software updates, then immediately make a new image. At the bottom of the text file I then just note "above done." Still have the record of changes. I usually only keep about 3 full images. Anyway, a simple text file works wonders if you just take notes.
