Since the "la grande odalisque"-tag doesn't give any information, I'd like to point out (for anyone who might find it interesting to know, for whatever reason) that this image is based on the 1800th-painting with the same name, "La Grande Odalisque". The original painting, which depicts a concubine, was made in 1814 by a French artist named Jean Auguste Dominique Ingres. It is known for being anatomically incorrect as the spine is too long for a "normal" human. Likewise, the right arm is longer than the left.
