I do have the info text, quite a lot, on the right of the preview screen and it is ideal and it is fast to run through individual previews.
However, when I'm running through the contacts the option of more info underneath the thumbnails would be helpful. What prompted me to ask for that is xnview at
http://www.xnview.com/ which is very easy to configure IPTC and other stuff under the thumbnail. Obviously if you are using small PM thumbs you won't see a lot but with the bigger thumbnails it would be really helpful.
One of the problems with the cataloguing program, Media Pro, is that the info under the thumbnail sometimes is not actually embedded in the image file. Which is the reason why I will sometimes use PM to run through the catalogued images.
