This seems to be a problem with a specific jpg file.
Could you please try to eliminate that particular jpg file from your book and then, export it?
It could be possible that particular jpg file is missing.
Hello, It is the same problem deliting the jpg file did not solve the error
Are all these images linked with their original images ?
Would suggest you to create a book with other set of images and try to export that for test purposes.
I had to check all the files
and 3 of them were damaged
you were right
then i could save the pdf file
thanks a lot
