How to delete images from entire Word document

[Xavier]

I have a very long (9000 page) .rtf Word document. It was created via OCR from 9000 pages of hardcopy.



Occasionally the text includes images (as per the attached image).

I realise there is the option of replacing all graphics with nothing, and that should delete all the images.

(As in find ^g replace [leave blank]).

Nonetheless when I do this it says there were zero replacements made.

This is driving me crazy, as clearly there are graphics inside the document.

Could the images I see be something other than graphics? How can I delete them all?
