And you're looking for a freebie. I'm looking for contributions , yes. Whether they're unpaid or not remains to be seen. Specifically, I am asking photographers and illustrators to license a few images for this educational purpose. I want a cut.
Every educational book costs money.
In fact, the only books that don't cost money are Dianetics and catalogues. Among other things, I'm not getting paid any more or less to include the chapter on adapted imagery, and I do not earn commission or any kind of marginal income with every image I use. I am not profiting from the addition of any particular image or even of a body of images. I came up with this idea. I am writing all the textual equivalents, which in itself is a massive job.
