I am currently in the works of making an ESL Book here in China. I spoke with customer service, and they said I would need an extended license. Though reading the standard license and alot of the comments, I am more confused than when I first started. People will not buy the book specifically for the pictures inside the book but the education value and English learning. The pictures will be used for the children to point at to say words like cat, dog, fish . . . which can be found anywhere on the internet. The Homework pages on the Adobe stock would be used to help them with their writing. The cover of the book will be two images from Adobe stock one under another. I also made my own logo to go over the top. So why should I use an extended license, when it states I can use a standard to sell books. I can see if I was going to sell a backpack with one image, or a poster with that image. So confused. Please advise.
