Image not appearing in PDF

Hi,

I've create a new document on Zoho Writer. The document has a number of images. On the first page of the document I've added a large image. It's like a cover photo.

When i export my document to PDF this image disappears. I've tried uploading the image again from my desktop but it still does not appear. I've tried export to DOCX and it appears there although wrong placing.

I really would like to get the PDF version working.
