I have a problem when, from indesign, I generate a pdf for printing

I'm doing a project in indesign and I have some pages from the catalog that are loading black, why?

I want to solve the problem of why a black background appears in the pdf for the generated print from Indesign instead of the image from the pdf?

I need to understand why this problem occurs, when you generate, no error appears?

I have a problem when, from indesign, I generate a pdf for printing, it appears in lile instead of images from pages black outlines, why?
