I've had quite a challenging experience getting the program going, but was able to figure it out on my own. There's a lot to like, but some really annoying and some upsetting things. I plan to do a complete plus/minus post when I get through this process. Right now, I have over 2300 images to now rename and images to add back to about 1000 pages of books.
One of the biggest annoyances is that it takes 3-4 MINUTES to add a new image. They are not large images, just a 160 pixel square thumbnails.
It's also crashed a few times. Probably due to hooking their star on MS .net framework - anything MS is buggy.
I'm running Win XP SP3.
