It appears that you have purchased an Open Cart theme and not a WordPress theme. That would explain why you’re having trouble uploading to WordPress. If you have made an error in your purchase, please open up a Help ticket and let them know all the details. Thanks!
Hello I’m not sure if I understand your question. If you are purchasing photos for use in a book you are going to sell, then an extended license would be required. Please see our PhotoDune License page for more info. Hope that helps!
