I have made a table in which a few cells have an image as background. On my Mac it works well, but if I preview the iBook on the iPad the images disappear and the cells get transparent. Can anyone help me?
Previews are rudimentary PDF versions of your book and often lack features, interactivity, etc.
Share/Export as an .ibooks file, save where you can find it, drag to iTunes and sync to your iPad. Test there.
