# Penflip updates, bug fixes, and ramblings

## Book cover images

A previous update gave you some control over the title page of your book, but a book doesn't really feel like a book without a proper cover image.

Good news: Penflip now has support for cover images! Simply upload an image titled either cover.png or cover.jpg to your project's images folder, and it will be set as the cover image when downloading as a PDF or ePub. Ensure that the image matches the dimensions of your book: 8.5x11" for Business books, Technical books, and documents; 6x9" for Fiction books. A high resolution (300 PPI) is recommended for best quality.
