Different ways to see a picture, pictures
"Flickriver" may show my photos on black background in interesting way, even if sometimes, I do not know how they are chosen. And I believe, each time it selects different one's, between the "most interesting" or...
Of course, one can see there photos of many others too. I like a lot how they display it. One by one, looks better in my opinion that the way one near other that Flickr decided to show them now. True, when you click on one, you can still see one by one and go to the next, and in bigger format even, but still, they are less well showcased.
How you communicate what you want to arrive to others counts.
