I am tagging my images and adding alt text tags in InDesign CC through Object Export Options and even adding Alt in the structure for my images, but when I bring it into PDF, the image is not tagged in the reading order and the alt text tags are not showing up. How do I correct this, outside of doing the work directly in PDF?
And just to add on a bit of information I didn't include above. I have a couple of legacy images included in the same document from previous iterations of the document created in a previous version of InDesign and they come out fine in the pdf document (fully tagged and alt text showing up).
I solved the issue - discovered that InDesign CC doesn't like mixing images from previous versions of InDesign, so took everything in the document and placed in a new document, exported to PDF and everything tagged perfectly!
