Online free art is a terribly broad and generic statement. With so many different styles and techniques to categorize art into, you will never see an end to art online unless you make the decision of what you truly want to see. Such online free art can be what you find in museums, visiting their specific sites, or it can be fan art based around a certain book or television show. It can be an online community of artists who have gathered to show off their talents and look at others, or it can even be in the form of a free online art magazine.
Free online art magazines are nice because they offer you more than just a picture. If you were to just casually browse classical art on a Google image search, you would get just that. Google images of classical art. Nothing more. But the different art magazines online will not only provide you with a variety of arts to view and experience, but there will be so much more. You can actually learn from an art magazine.
Things may differ slightly from one magazine to another, but they are all there for you to appreciate art, learn about it, and even learn about why you should appreciate it. The goal is to create more art fans, not ostracize those who do not yet understand art.
One of many online art magazines has a series of tabs on its site. One is dedicated to News, relating to both old and new art and artists. It keeps the reader informed on all of the developments in the art world. Another page on their site is Trends. This can cover trends in the actual, physical production of art, or it can address the trends found in the art market at the time. There is also a section labeled Features, and that is just like as if it were an actual print magazine. You can find feature stories there, with things like artist interviews, discussions of new exhibits, or emerging styles in the art scene.
There are plenty of articles and stories, all tied into the art world, in just a single online art magazine site. Explore. Learn. Grow to appreciate why things are revered or reviled in art, simply by reading about it at one of these magazines. With constant updates and an ongoing cycle of news, things will never be stagnant or old with this art.
