I originallysubmitted the images 4 months ago and all was good. This issue started with me a week ago. I've deleted the images and replaced them with resized images five times. Each time I replaced the images I made sure I conformed to apple specs. I still have this issue. I have not replaced the image with jpegs. I'll try jpeg images next if Apple Help cannot find a solution. Any solutions out there? I'm all ears.
