Indesign technical issue
I am working in InDesign 2024 and I work on the Mac platform. I completed a project for a client, who asked for the files so she can make simple edits to text. I sent her all the files via dropbox, and she uploaded them onto her computer. She is using a PC, also InDesign 2024. She noticed when she opened the file, that the cover image was blurry, the rest were fine. I thought that was odd, but noticed that there was the same image in the file that was used on another page that she was able to see clearly, so I replaced the front image with that image and resent it to her. Now not only is the cover image still blurry, other images became blurry when viewed. Her display setting is on high res, so it does not make sense that some images are fine, some blurry. We tried relinking the images, etc to no avail. It is perfectly fine on my end. Any suggestions?
