Python Insert Image into the middle of an existing PowerPoint
Question: I have an existing PowerPoint presentation with 20 slides. This presentation
serves as an template with each slide having different backgrounds. I want to
take this (existing) PowerPoint presentation, insert an image in slide number
4 (do nothing with the first 3) and save it as a new PowerPoint presentation.

This is what I have up until now. This code loads an existing presentation and
saves it as a new one. Now I just need to know how to use this to insert an
image to slide number 4 like described above.

Note: I am using normal Python.

    
    
    from pptx import Presentation
    
    def open_PowerPoint_Presentation(oldFileName, newFileName):
        prs = Presentation(oldFileName)
        #Here I guess I need to type something to complete the task.
        prs.save(newFileName)
    
    open_PowerPoint_Presentation('Template.pptx', 'NewTemplate.pptx')
    


Answer: I'm not really familiar with this module, but I looked at their
[quickstart](http://python-
pptx.readthedocs.org/en/latest/user/quickstart.html)

    
    
    from pptx.util import Inches
    from pptx import Presentation
    
    def open_PowerPoint_Presentation(oldFileName, newFileName, img, left, top):
        prs = Presentation(oldFileName)
        slide = prs.slides[3]
        pic = slide.shapes.add_picture(img, left, top)
        prs.save(newFileName)
    
    open_PowerPoint_Presentation('Template.pptx', 'NewTemplate.pptx',
                                 'mypic.png', Inches(1), Inches(1))
