PPTX Image Updater

Do you know when you have a Powerpoint that you present often and it has a couple of diagrams that constantly get outdated? This tool allows you to update the images inside a powerpoint (PPTX) with up-to-date versions obtained from valid URL sources. You do this by associating a hyperlink with each image that you want to target and then just running this command

Getting Started

Setting up this command locally is very easy

Prerequisites

This tool requires python installed (compatible with either 2.7+ or 3.3+).

For additional info please refer to https://wiki.python.org/moin/BeginnersGuide/Download

Installing

• Start by cloning this repo to your computer

• Install python-pptx module

pip install python-pptx

• Navigate to the newly created folder and run the following command to validate that it's working:

python update-images.py -h

This should display the various usage options of the tool

How it works

The concept of this tool is very simple:

• you have a PPTX which includes images which you want to update from a certain source

• each image that you want to have automatically updated should include a hyperlink to the relevant source

• then just run the tool like:

python update-images.py <yourfile>.pptx

• it will automatically:
  • open the file
  • iterate the various slides
  • for each image validate that it has a hyperlink
  • if so, download the image from that url and update it on the slide
  • save the file again

Authentication

Some images might be on the intranet under some sort of authentication. This tool also supports sending basic auth data by supplying the --username (-u) and --password (-p) parameters

python update-images.py <yourfile>.pptx -u myuser -p mypassword

If the password has special characters (like '!') it should be placed under single-quotes, like:

python update-images.py <yourfile>.pptx -u myuser -p 'mypass123!!!'

Known Limitations

• Only supports PPTX files, not PPT

• Currently only basic-auth is supported. If you need another type of authentication it would need to be implemented

• If you duplicate the same image on the PPTX file and assign them different hyperlinks, it would update both images with the same data, particularly due to an optimization done by Powerpoint, on which it stores both images blob on the same place
