See GLAM/Metropolitan Museum of Art on English Wikipedia for WikiProject coordination with the museum, and future plans.
And in particular, check out The Metropolitan Museum of Art makes 375,000 images of public domain art freely available under Creative Commons Zero on the Wikimedia Blog.
We welcome your perusal and use of the artwork photographs in Category:Images from Metropolitan Museum of Art.
We are pursuing both mass uploads (organized centrally) and individual uploads by the community for the time being.
If you wish to upload your particular favorite artwork, we ask you to format your file description page like the Frog Pendant example, and utilize {{TheMet}}, Institution:Metropolitan Museum of Art and Category:Images from Metropolitan Museum of Art, with the description field as "Object name; Culture; Classification" and with the filename as "File:Title MET ImageID.jpg".
Hold off on mass uploads for now, which we are coordinating and planning together.
