The toils of the original authors are robbed and exploited, and the general quality of the Web is diminished. Everyone ends up looking like a crude and intellectually dishonest thief. None were stolen from any other web site. All were scanned or digitised by me or by colleagues acting on my behalf. All were painstakingly generated, cleaned and edited exclusively for use in this web site.
Credit is given for files created and provided with the assistance of others.
Every image was obtained in order to illustrate a particular point of technical discussion. Each image represents at least an hour's worth of work in acquisition, editing, cataloguing and integration into the appropriate web pages. Therefore I only accede to requests for donation of images to other web authors under the most extraordinary circumstances. So too is the content and form of expression of my web pages. I will treat all instances of plagiarism, poaching and copyright violation with great seriousness.
