How to separate images
I don't know if I'm saying this correctly. When you purchase stock images (backgrounds) that have multiple images (backgrounds). How do you separate them so that you can use 1 of the 3 images that you really like. I am trying to make a book cover but I licensed a collection of 3 but I only want to use one of the backgrounds. How do I separate it from the collection to use the one I want. Please explain the steps or process. I am a beginner with adobe illustrator, indesign and photoshop. Any help will greatly appreciated. I have attached an example
