If the medium and/or materials (e.g., oil on canvas) are important to the reference, you can include this information at the end of the entry. However, it is not required.
For photographic reproductions of artwork (e.g. images of artwork in a book), treat the book or website as a container. Remember that for a second container, the title is listed first, before the contributors. Cite the bibliographic information as above followed by the information for the source in which the photograph appears, including page or reference numbers (plate, figure, etc.).
