Nope, that's just one directory. I was just illustrating the one photo sharing piece... which is as simple as drag a folder into Dropbox, and go to the web interface and click share.
I have approx' 40k photos (not including the .raw files) over about 180GB (including the .raw files).
I need a solution for on the order of 40,000... for which Flickr is perfect, since there is no storage limit, just a very small flat fee.
