If you have been downloading a lot of the free iBooks, you have probably noticed some boring Book covers. Those covers are easy to change.
If you’ve ever added custom album artwork to an iTunes song, this will be very familiar. If you haven’t, here are the steps:
You can do a image search from Google or whatever search engine you use. Amazon is also a good choice but keep in mind these are most likely copyrighted, and their aspect ratio will probably not match the default aspect ratio of the book covers from the iBookstore.
Keep in mind you can add any image for your book cover and modify it with your image editing software. You can add text over the image for the book title, etc. The image will need to be about 420×600 and save your image as a high quality JPEG file. Add the cover in iTunes with the steps mentioned earlier and your done.
