OK.

You get the "correct" behavior :) The trick is : you write text and text
and text. Sometimes, you want to add a picture but you don't want a page
break. For example, you want to add a big illustration. To render
correctly, the picture needs its own page but you don't want to break
the page. In this case you need to anchor the picture to the "page". I
made an example based on the road book I'm working on :
http://www.jerryland.fr/tatw/WorldTrip.odt. Quick example visible on
pages 20 and 23. For information, the first map inclusion was at the
beginning of 2.1.1 and the second map inclusion at the beginning of
2.3.1.

Obviously if you anchor consecutively two pictures to the "same page",
you could be disappointed by the result but it's an issue you have to
address with some others parameters which I do not know actually.

Finally the patch I was talking about is not this one but the one
attached to http://comments.gmane.org/gmane.emacs.orgmode/49548. I
really need it because this bug lead to at least 50 seconds more to
generate my ODT file.
