InDesign CC 2018. Creating accessible pdf files. You are supposed to anchor images in the text flow, and they appear in the appropriate places in the accessible pdf. In InDesign CC 2018 the exported pdf does not contain the images that are anchored in the text.
I tried the same file from InDesign CC 2017 and the images were there.
This is a bug which needs to be fixed.Doug Jeans supported this idea ·
