run.add_picture() won't insert the image into the document

I’m trying to editing an existing Word document (.docx). Everything works well and I can easily add images at the end of the document with : document.add_picture("my_picture.png") .

My problem is presented when I try to get a specific paragraph and add a picture inside a new run.

ex. document.paragraphs[20].add_run().add_picture("my_picture.png")

The command executes correctly, but then when I open the saved word document no image is present at the paragraph n.20.

Post the before-repair and after-repair XML and let’s have a look:

paragraph = document.paragraphs[20]
run = paragraph.add_run()
picture = run.add_picture("my_picture.png")
print(paragraph._p.xml)

Then after the repair:

paragraph = document.paragraphs[20]
print(paragraph._p.xml)

I was able to cope up with the error by not using paragraph spaces before and after. So, I think there is a problem in either line_spacing or space_after methods. Adding to that I was also not able to add picture using document.add_picture() call as stated in issue.

paragraph_2 = document.add_paragraph()
paragraph_2_run_1 = paragraph_2.add_run('Test Graphs: ')
paragraph_2_run_1.bold = True
paragraph_2_format = paragraph_2.paragraph_format
# paragraph_2_format.line_spacing = Cm(2)
# paragraph_2_format.space_after = Cm(1)

paragraph_3 = document.add_paragraph()
paragraph_3_run_1 = paragraph_3.add_run()
paragraph_3_run_1.add_picture("Test_Graph1.png")

When adding picture forcefully in word application it appeared to misbehave and inserted picture under text. After that, saving the document generates error.
