Can I turn my own photo into a color by number page?
Yes. Click "Photo page" at the top of the Designs column and choose a photo (JPEG, PNG or WebP). A page called "Your Photo" is added at the end of the book: the photo divided into regions of its own colors, every region numbered, the colors named in the key. A large photo is reduced to 2048 pixels on its long side and kept in the book's "art" folder.
