VSA Arts has an online exhibition of Art, Disability & Expression.

As well as showing many examples of visual art it also examines some of the history and culture of disability as content.  There are some powerful and fine images in the exhibition.

VSA Arts has an Artists Registry which is free to join. Represented on the registry are artists with many kinds of disabilities including chronic illness, chronic pain and long term mental illness.

The web site also has many resources for artists on the site including opportunities, career development tips (including advice on photographing work, pricing, sample contracts and more), various publications and resources for materials, adaptive tools and instruments.
