If you’re going to self-publish a print copy of your book on CreateSpace, you’ll need a cover image. You can either do-it-yourself or find someone that can do it for you. If you’re not graphically inclined, finding someone to do it is your best route, but I encourage you to learn the tools of the trade because it will allow you to create promotional and website graphics yourself.
If you’re going to prepare the cover image yourself, you’re going to need Adobe Photoshop or Adobe InDesign. If you don’t own either of these products, I recommend getting Photoshop. It’s only $9.99/month and a lot more versatile for creating other graphics you’ll need as an author. InDesign is the right choice if you’re going to use it for your interior as well. I used Microsoft Word for my interior and it turned out just fine.
Step one: Before you commission artwork, search for a stock photo or start drawing the art yourself, head on over to CreateSpace and determine the dimensions of your book (width and length of the front cover) a.k.a. trim size and how many pages your book will contain.
