Image copyright notice in EPUB exported images removed by ID
If you create an InDesign ePub that contains images with copyright notices, inspection of the exported image files within the EPUB (ie. OEBPS/image/*) shows that the embedded images have had the copyright notice removed.
Ideally, copyright messages should be retained throughout the export process.
The TIFF source file has an IPTC Copyright message.
