Internet galleries are doing well in times of economic growth
Artwork changes ownership.
This is done through internet galleries that breed like mushrooms after the rain.
Let's name the greatest or at least the most visible.
All these galleries offer the sale of images in online auctions. Sale in the form of an auction usually takes place in a way that works are exhibited for a certain period of time (some may already be bidding, then) and then a "sharp" auction, when all running auctions will end during one or two evenings.
