An online art gallery is an online version of a contemporary art gallery. The increase in broadband adoption, and the improvement in web programming techniques opens up the opportunity for a better visualization of online art. While no online gallery is still using light filtering effects, and 3D photography is not yet available, much richer images and improved visualization techniques provide the viewer with a much richer experience.

The viewer can be offered the option of zooming so that texture or pigmentation can be examined. Also in some cases the size of the work can be better appreciated by showing it next to an image of a person of average height.

Another advantage of online galleries is that the public art buyer is expanding, but people are still somewhat intimidated by most commercial art galleries. They think they do not know anything about the art and I think in some cases this harms the sales of some artists. If the potential buyer has access to a wide range of art they can see in the comfort and safety of their own home they tend to look a little deeper and get to know what and who they like.
