The Web Gallery of Art was opened in October 1996. Since then many changes occurred which are summarized on the What's New page of the original version designed for large screen with resolution of 1024 x 768 or higher.

Major change in November, 2011:

• An experimental version designed for small screens (for mobile devices) was introduced. It is intended for use on screens with resolution of 320 x 480. This version is based on the entire database of the collection (over 27.600 reproductions in August 2011), but some of the advanced services of the standard version (guided toures, dual mode, postcard service, music service) are omitted.
• The catalogue of the entire collection can be downloaded in various formats from the mobile version, too.
