The gallery announced Thursday that more than 20,000 of its works have been assembled into an online resource called NGA Images and anyone, for free, can search, share and download.

Say you want to create a gallery of women, because March is Women’s History Month. You might start with Edouard Manet’s “The Railway,” Mary Cassatt’s “Children Playing on the Beach” or Jean-Honore Fragonard “Young Girl Reading,” Renoir’s “A Girl With a Watering Can,” or Judith Leyster’s “Self-Portrait.”

The possibilities of categories are only limited by the NGA’s esteemed vaults.

The gallery has the only Leonardo da Vinci in the Americas. Now professional and amateur collections can share “Ginevra de’ Benci.”

Artists include: Raphael, Rembrandt, Vermeer, Gauguin, Monet, Titian, Homer, El Greco, Cezanne, Degas, Seurat and Toulouse-Lautrec.
