I haven't been able to get the press release section of the National Portrait gallery to load, so I'm linking to an email from the NPG posted as a comment on another blog. I'm still thinking this through, but currently the important bit, to me, is this:
The Gallery is very concerned that potential loss of licensing income from the high-resolution files threatens its ability to reinvest in its digitisation programme and so make further images available. It is one of the Gallery’s primary purposes to make as much of the Collection available as possible for the public to view.
Digitisation involves huge costs including research, cataloguing, conservation and highly-skilled photography. Images then need to be made available on the Gallery website as part of a structured and authoritative database.
Obviously, I am paid by a museum to put things online so I might be biased towards something that ultimately means my job exists – but while a government funding gap exists, someone has to pay the magical digitisation fairies. [This doesn't mean I think it's right, but the situation is not going to be changed by an adversarial relationship between WMF and the cultural heritage sector, which is why this whole thing bothers me. Lots of good work explaining the Commons models and encouraging access is being undone.]
You can't even argue that the NPG is getting increased exposure or branding through the use of their images, as there's a big question over whether images hosted on Wikimedia are being incorrectly given new attribution and rights statements. Check the comment about the image on this blog post, and the Wikipedia statement from Wikimedia about the image and the original image page.
To use a pub analogy, is Wikimedia the bad mate who shouts other people a round on your tab?
