I've been creating indexes in Word using thumbnails, often uisng the .pngs created for Poser thumbnails by the content creators, sometimes creating my own thumbs if I don't think the supplied thumbnail is gives a good enough view of an item. I've indexed about a third of my content and have had to split things into 68 Word files (since Word chokes on these indexes when the file gets over 20 Mb in size) and the total size is over 800 Mb. It's taking a ridiculous amount of time, but it does make it easier to find the exact items I want to bring into an illustration. Since I'm doing it while watching TV, it's not exactly lost time.
