ERROR ITMS-9000 Not listed in the OPF manifest
Image Data are rearranged the item name in iBooks Author. However error message shows several images are not listed in the OPF manifest. Obviously I cannot touch the OPF manifest file directly. And I cannot identify which image has the problem. How can I solve this error?
