Thanks, that's good to know. I'm also wondering how those who publish things like cookbooks go about using images in their ebook. Can you just use images of the dish from Google or what? From looking at reviews I sense that a lot of people expect images of the final product if you're publishing recipes. I'm not much of a cook so actually cooking something and taking a picture is out of the question for me!
I think you can't use the images from Google. You wold need to get a permission from the authors or buy royalty free images.
