One of many many many shortcomingsÂ… yes. You'd think that InDesign would do a good job given that it's developed by the same company that invented PDF, but...

This approach isn't great because some kinds of AT won't handle such a workaround very well - magnifiers (that use tags) won't see the caption, for example.

Do the captions not follow directly after the photos in the structure tree? If they do, then why wouldn't your originally proposed approach be acceptable?
