While not exactly fulfilling its title, The Story of British Art is nonetheless an interesting series of articles, accompanied by an image slideshow, on artists from (or related to) British history by Guardian art writer Jonathan Jones.
While I don’t always see eye to eye with Jones, I always find his articles worth reading, and he usually has something interesting to point out about the artists he covers.
The individual articles have larger images, many of which can be enlarged. The slideshow is somewhat the opposite — starting with close-up crops that can be zoomed out to reveal a smaller image of the entire work with a control at the upper left of the image.
