I think that the reason most of the major collectors don't contribute to these sorts of things is because they don't want to deal with the attention. I mean, I know a lot of guys who won't even acknowledge that certain pieces are in their collections. They don't want to deal with all the annoying questions and offers to buy their stuff. So they just share within their little circle. Then there's the "I can't believe you paid $1000 for a piece of plastic" crowd they'd have to hear from. So why go through the trouble of taking the photographs when the only people who will appreciate them don't stray from the RS Vintage forums?
I've considered sending in photos myself, but always end up thinking "Do I want everyone who goes to RS to know I have all this expensive stuff in my house?" And I always come to the same conclusion.
That's a great point.
I personally have probably less than 20 vintage figures in my collection, and they're all from when I was a kid. They're played with, loose and worn. I plan on putting them in some sort of shadow box and hanging them on the wall, but that's something that would only be special or interesting to me and those who know me well.
My modern collection is pretty much complete. There's a handful of things I don't have, like force flippers and Toyfair Vader, but I do have a very comprehensive loose collection. Sure I have a few odds and ends that will remain packaged, but the majority is loose.
When I submit pics of my collection, I'll include the things that I feel the community here would like to see. And I won't submit until I have things assembled in such a way that (hopefully) people will enjoy seeing.
