It contains an example of markup to create a full page image. Use that markup and you should be fine.

Thank you! I saw an old forum post where you suggested using the "full page" option when uploading an image and I tried that but when I check the book on kindle reader on my phone the image comes out stretched vertically. But I'll read the manual and see if it makes a difference. Thank you for responding!
