Make sure your book cover is displayed!
On BookFunnel Landing Pages
Upload your book cover when you create your new book. The JPEG book cover will be displayed on your download pages, email signup pages, group promos (if you join promos), and in the BookFunnel app. Learn how to upload your book cover.
In the Kindle App or Other Reading App
When you create your EPUB and MOBI files, be sure to embed the book cover inside the file. The steps to embed the book cover will vary, depending on the service or software you use to generate your book files, but all ebook publishing software can embed your cover in your book’s metadata.
If you embed the book cover, readers will see it when they download the file and send it to their reading app. If the book cover is not embedded, readers will see a generic square instead of your book cover in their reading app’s library.
For a PDF, you can make the first page of the file your book cover and it will look like a book cover when viewed in a file system.
Blank cover on Kindle or Kindle app
If your cover is embedded, it should be displayed on all Kindle apps and devices. If you used Amazon Send to Kindle and the book cover in your Kindle library is generic, try opening the book. That should pull the cover from inside the file if it was embedded in the metadata.
