edited pictures from my client are not visable

Hey everyone, I have a problem with the catalog that my client sent me. I´m editing pictures for him, he edits a few of the galerie and sends me the catalog so I can edit the rest of it. He sent me the catalog, but the edited pictures will not show up. Am I doing something wrong? First time it worked perfectly but nor something is diffrent and I just dont get what I´m doing wrong. Anyone here who can help me?

Thank you!
