I'm not sure there is a 'moral' issue. There must be thousands of 'similar' pictures out there. I propably have many dozens of them myself, burried in my archives, B & W from 30-40 years ago and more recent color slides and prints. Besides, IMO your image is not even close to nongo's. The only thing in common is the subject and maybe the evergreen trees in the background. The pictures are by different artists, taken at different times, in different place. Go ahead and post it. I won't pass judgement on either, I like both...
