Here's a 20-min. video that Peter Krogh, author of The DAM Book: Digital Asset Management for Photographers (link at left) prepared on how to set up ImageIngester Version 2 the way he recommends (requires Adobe Flash 9).
Most of what he explains is also perfectly applicable to Version 3.
ImageVerfier Documentation
ImageVerifier is documented on the ImageVerifier page (link below and at left) and also in the ImageIngester 3.1 and 2.3 User's Manuals (see above).
New features in Version 1.1.02 and newer versions are on the ImageVerifier page.
