did you sure you are here where you think you are ? and not at the end 
off the wro,g paragraph
trye
# Move the cursor xTextCursor.gotoPreviousParagraph(False)

  xTextCursor.gotoPreviousParagraph(False)
xTextCursor.gotoNextSentence(False)

hope it helps

The image is indeed anchored to this position, as I can see when I manually insert some more text before it. So it is not a matter of an offset.
