I exported a fixed-layout ePub document in InDesign CC and receiving an error when submitted via iTunes Producer that "images larger than 4,000,000 pixels are not allowed in books." (see attached)
I looked into the contents of the ePub file to see which .png files are causing the issue, but they are just frames filled with a solid color (and not an image) in the original InDesign doc. The .png files themselves are small, e.g., 22 kb, 45 kb, 60 kb.
Any suggestions what might be happening here (and how to fix it)?
