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.

Line setting the limit

The boolean condition is reversed. The limit should be set to what the user specified, or, 5000 if not set. So the correct code should be: $limit = 5000 unless $limit; The Perl code enforcing the limit also has another bug. If the limit is less than the per_page value (e.g. 500 in the book), then 500 images are returned anyway.
