Up until a couple of days ago the license on all the images was restricted, though you could ask me for permission for a license. I’m not sure why I set the license that way, though I think it might have been a few years ago when I was constantly finding people ripping off my content..
In any case I’ve changed the license on most of my photos and images to be:
Creative Commons Attribution-NonCommercial-ShareAlike
The only exception being the “Blacknight images” set, which is mainly made up of images that we have produced for marketing etc.,
