What all the artists share is an interest in the notion of appropriation of images.As far as art history is concerned this is a familiar enough idea. From the early Christians who nicked pagan imagery, through the Renaissance artists who lifted straight from the Greeks to Picasso who begged, borrowed, pinched and incorporated from all over the place, appropriation is merely - as someone else said - stealing from thieves.

But where once the act of appropriation was something that an artist did to make a specific point, now, in our postmodern world, it has become the norm. The camera is ubiquitous in our lives.

Art is certainly not going to offer an answer. Is it even art? Or is it just so much stuff, as Leckey, in his work, asks? It is questions such as these that make Dispersion worth seeing. Because even as they undercut all the prescribed meanings, they leave you more room to decide for yourself.
