I am creating a coloring book and wanted to know if I am able to use the images I purchase to publish and sell. I am not a professional graphic artist and all of this is new to me. Do I need a special license? I alter them and collage inside images I create and want to self-publish if possible, but can't afford a lot due to disability. I don't want to misuse artist's work. Thanks!
You would need the Extended License. You can get those through fotolia.com for the same images on Stock. Just search for the Adobe Stock image number.
