Hi George
Welcome to the wild frontier of digital publishing, they don’t make it easy do they?…
In cases like this Google is your friend. ERROR ITMS-9000 shows you have a file in your EPUB that is not meant to be there and ERROR ITMS-90228 shows you have five images larger than Apples’s 4 megapixel limit.
There will be more information after the error code that points you directly to the problems, albeit in a unfriendly code way. Let me know if you need help deciphering these…
You can fix individual image output sizes using InDesign’s Object export options. Here’s a video on that https://helpx.adobe.com/indesign/how-to/indesign-object-export-options.html if you need to control image sizes for an entire book in one place then you can use the Boilerplate JPEG options in my company’s software CircularFLO More info https://www.circularflo.com/userguide/?mp=Client3333/Job1000/034 and free trial here https://www.circularflo.com/download/
If the ITMS-9000 error lists the file name ‘iTunesMetadata-original.plist’ then it has probably been (very annoyingly!) introduced by iTunes itself when previewing the book. Try only opening in iBooks and not through iTunes to get around this.
Good luck!
