Ovid's "Metamorphoses" has been an inspiration to many artists down the centuries.
Larry A. Brown calls the pages from his site devoted to the "Metamorphoses":
An introduction and commentary with discussion of myths and links to sources and influences in art and literature.
This German high school site has the Latin text, broken down into sections with German, English, and Spanish headings, and copiously illustrated with artworks, mostly but by no means all, prints from early printed editions of Ovid. In the side panel click on Ovidius Naso Edition, and then scroll down to the index of the 15 books. Those with slower connections may need to be patient.
Not specifically linked to the "Metamorphoses" but with further information about the characters, with citations from ancient sources and illustrations, are: theoi.com and Carlos Parada's Greek Mythology Link.
