As with many things that are a result of some visual skills married with ideas, they may or may not be art and they may, if they are art, be good art or bad art.
The problem is that a tendency exists to classify everything of a type as either art or not art when in fact, it may actually depend upon the purpose for which it, the product, had been made.
Someone makes a print for a classroom wall as an example of how a particular plant looks in its natural environment. Is that art? Another time, that same picture is placed within an exhibition. Is it then art? Does the place where it's being shown create the art, if it exists at all?
The volume of hot air that we have collectively blown here on this topic over the years makes further comment pointless.
