Hi Philippe & everyone,

I've been reading the posts for a few days but felt too imitated to ask
anything. First, I gotta say, Philippe, you must be a genius the way you
developed a virtual tripod. What a great idea.

I've been struggling with little to no success using Panorama Tools
(WINDOWS) for a few weeks and have learned alot of terms (I even understand
some of them now) and lost a significant portion of my life trying to figure
out what I was doing wrong. I tried your approach below and even got the
script to run. But the pano never developed and the output was
horrendous. If you don't mind, I'll try to show what I did inside your email
using (**   **)
in hopes of learning what and where I went wrong.
