Hi Kate, Speaking from an NZ perspective here. I've found that in NZ institutions tend to limit access to higher quality images and have separate licensing on these (rather than copyright). You are free to use the web published version but if you want anything extra then you need to jump through hoops to get a high res version, possibly pay for it and agree to restrictive licensing terms. It is changing but only slowly.
Also in response to this comment: "There can be no valid copyright in images that are merely "slavish" reproductions of two-dimensional works, no matter that some institutions may continue to make such claims. So with respect to those "slavish" types of images, questions about resolution and size are simply irrelevant from a legal perspective -- and no CC license attached to any such image could be valid." Maybe in the US but in NZ organisations are claiming copyright over scanned photos and other images. I don't think this has been tested in court. IANAL so I don't know if they have valid claims or not. Thanks, Glen
