Wishgranter,
mainly because I find the different problems people encounter quite interesting and it does benefit the community alot, when possible solutions are posted and discussed.
It's very nice of you to spend your private time helping the people, but think about it, when doing it publicly alot more people might benefit from your knowledge and not just a single person via email.
And if someone is working on a top secret project, he/she can describe the problem in detail and does not have to post pictures. Or maybe then just contact Agisoft support.
Cheers.
