Where can I upload my cover image?

Upload your cover image file for your NOOK Book from the Cover Image page. Your cover image must be a .jpg or .png file with a file size between 5 KB and 2 MB, and the height and width must be at least 750 pixels. However, for optimum quality, we recommend that both the height and width are at least 1400 pixels. If your cover image does not meet these specifications, then you must use image-editing software to stretch or shrink the image. Remember, you must have the rights to use any image that you upload.
