"The pragmatic reason I don't post here is that I'm not interested in having my images scraped and circulated and perhaps having their ownership stolen".

Bingo.
I have some images I quite frankly don't know what to do with - socio/political, religious.

With a couple of them, when I was with a former photography group with some Excellent fine art photographers, graphic artists and media personnel, i.e. professionals, within one showing at a month's end critique, one of the more experienced members, as he got to presenting and critiquing my effort, said " I've been waiting all evening to get to this one. An image hasn't moved me as this one has in quite some time".

This is not an attempt at bragging as I have been honest in my assessment of others' beautiful and gorgeous work; both in color and b&w. With the current system of holding on to presented images to 'time infinitum', I don't care to have my work copied, distributed, or stolen: either domestically or foreign. And allowing such MB sizes allows for download theft. Simple. Maybe in time I will reconsider and start with a couple of more mundane images.

The purpose of my involvement here quite simply is to learn what I don't know, and to help where I'm able to the extent of my abilities, at whatever level I'm at.

To say that not to post images is unsupportive, I heartily disagree. Yet, as in any forum, I take opinions to heart as we all see things from varying standpoints. Gee, that's what makes us photographers, no? This is simply my take.
