invoice records image fields not displaying in PDF


I have custom fields of type image in my invoice module. They display fine in edit view etc, but when add them to a PDF template type do not display. It just puts a red x in the PDF file.

any guidance would be happily received.

This is also happening to me:
I guess it’s the same issue…

It’s not quite the same. I am inserting a field of type image. This does not display in the pdf. It appears the file name is not correct it is missing the record Iid at the start.
