Hello, I'm new on this forum, so excuse me if I'm not in the right section or if there already is a topic on this subject. Also excuse me for the poor quality of my English (I'm French so please correct my grammatical mistakes). Recently, I've been thinking on writing a book about bodybuilding, in which I would give to anyone (beginners, intermediate) a 6-month muscle building program. As I'm on a mac, I've downloaded the app iBooks author, which works great and is well-designed. However, I have many questions about publishing on the iBook store (you must publish your book on iBook store if you use iBooks author, and nowhere else): 1) Is iBook store a good place to sell books? I mean, I had never heard about this store before, so I'm wondering if I will make a decent amount of money (for a beginner). 2) How much money should I expect (on average)? 3) Can I use pictures found on Google Image to illustrate my book? If not, how can I know if a picture is protected by its owner? 4) Are there other better means to get my eBook published (it seems like the Kindle store is pretty huge)? Thank you for your concern.
