Google has expanded its Art Project which allows users to take a virtual stroll around some of the world's most famous art galleries.
Launched last year offering 360 degree tours of 17 museums' collections, 46 more institutions have now signed up.
The project uses Google's Street View technology to provide high resolution images of paintings, sculptures and photographs.
More than 30,000 objects can now be seen in detail.
With images larger than a gigapixel (one billion pixels), a zoom-in feature allows viewers to get inside cracks in the parchment and other details that are not visible to the naked eye.
In the UK, new additions to the project include the Victoria And Albert Museum, Royal Collection and Imperial War Museum.
Dulwich Picture Gallery, Serpentine Gallery, National Galleries of Scotland, the Jewish Museum, the Museum of London, and the Walker Art Gallery, Liverpool have also signed up.
They join Tate Britain and the National Gallery which are already involved in the project.
Viewers can now also look at the White House in Washington, the Museum of Islamic Art in Qatar, and the Santiniketan Triptych in the National Gallery of Modern Art in Delhi, India.
"From now on anyone can visit these great institutions with just the click of a mouse," Google President Margo Georgiadis said.
"This project breaks down all of the barriers and allows people to study art in a seamless way."
Google has also signed partnerships with 151 other institutions in 40 countries to show objects in their collections.
