large X appear on new pages in iBooks Author

I am preparing a textbook with several figures and text.

After about 40 pages the file is 60 Mb but the problem is that every new page I create has a large X covering the page.

The large X also appear in the PDF export. In the iBooks preview, though, a small "?" sign appear on top left of the page...

What does it mean?

How can I solve this?

Thanks in advance

Thank you for your reply.

In fact I did find 2 warnings telling me:


Missing File letterpress_paper_1536x2037-6.jpg


and


Missing File letterpress_paper_1536x2037-9.jpg

but I think I have never used such files in the document. I also searched my HD for them without success...

Is this kind of file an internal library file of iBooks Author that is for some reason messing?


Note that now I get this error on each new page I insert, regardless of the position where I try to put it. All the existing pages instead do not show warnings or large X over them.


Thanks again,

Filippo
