There is more to art then one can think. the imagination is a really vast and endless place. I think that art is an expression of ones own feelings, because there are so many thing in this world that a person can't explain through words. Art gives joy to people as well as sorrow. It is a way of communicating with others about an idea, a feeling and more.
You look at a picture and there is so much you can tell form it. The problem about art is that it can sometimes be overwhelming because one picture can mean so many different things. It is important to not get swept up into what the picture should mean but what you feel it does mean.
Art is also not subject alone to pictures, it is music and even writing in my opinion. It is any form of communication that can express more than just words. It is important not to lose art from the world because it is a crucial part of communicating with other people.
Last note. That the cool thing now a days is that art is expanding with the technology that is being developed. It is really cool to think that with the advancement of science allows for more expression with art and more expression creates more ideas and more ideas will be able to advanced art and technology to the next level.
