I have a Writer doc with a registered image (i.e. the image has the (r) symbol) in it; and when I export to pdf, the image isn’t in the pdf. I’ve searched all around on this topic and haven’t found anything. Any help would be greatly appreciated.
Have you tried with another image? In the Export dialog, Selection remain checked inadvertently?
