Hi @dylan mack,
Yes, it is possible to update pictures in PowerPoint automatically using third-party software. One way to achieve this is by using PowerPoint Automation Services in SharePoint, which allows for server-side presentation conversions to and from a variety of file formats. Another option is to use PowerPoint add-ins to add dynamic HTML5 content or bring in reference information to your presentations. Additionally, PowerPoint for the web allows you to work with presentations directly on the website where the presentation is stored. However, the specifics of how to link PowerPoint to a third-party software to automatically update pictures would depend on the software being used.
