Flickr Hacks by Paul Bausch and Jim Bumgardner The unconfirmed error reports are from readers. They have not yet been approved or disproved by the author or editor and represent solely the opinion of the reader. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification This page was updated February 20, 2008. UNCONFIRMED errors and comments from readers: {xix} 2nd paragraph; The code location is now: http://examples.oreilly.com/9780596102456/flickr_hacks_code.zip [67] first paragraph; The authors give the url for the Merode Altarpiece that the art history students put together. The group is private and cannot be viewed by the readers of the book. This especially unfortunate because an example is needed to be able to visualize how the collaborative function being described works. Author's note: The example was public at the time of writing, but Flickr allows users to make photos private at any point. I agree that it's unfortunate that the example has been made private, but that's one of the hazards of writing about a changing landscape.
