The reference to my STACK figure animations is correct, but these figures were superseded some time ago by the ISKCB figures:www.reeddesign.co.uk//iskcb/index.html
And Lateral roles
should be Lateral rolls
Thanks Roy. I will fix these. Hopefully should appear in an amended edition in about a month's time. (I update the document more often than that, but don't want to ask the webmaster to upload a revision too often.)
And, yes - you should certainly be asking permission to use any material (photographic or not) that is someone else's copyright - especially as you are claiming copyright on the document yourself.
Sorry. I must not be clearly stating the issue.
For the record, to the best of my knowledge, there are no photographs or text in the document that have been created by others - And if I start adding them, I will seek their permission.
The issue regards me taking photographs of others, or more specifically, their kites. So far, as far as I am aware, I have avoided taking photos at events where the organisers forbid it. But suppose I took a photo of your Gemini or Nirvana at the Streatham kite festival? (I don't think I did, but it's a good hypothetical.) Suppose I include a picture of the kite within the notes? Suppose I include a picture of you flying the kite within the notes? Suppose I include a picture of a number of people including yourself flying kites within the notes?
And suppose I go down the Lulu route and create a document that people pay for??
That's the sort of issues I am worried about.
