Time to time we may find a PowerPoint presentation which contain images embedded in the Slides which we would like to save, but the problem is that when we have the presentation file (PPS) we can’t just copy the image and save it in a new file.
The process is quite simple; you just have to export the powerpoint Presentation to a web page (HTML).
Click on File > Save as… and select a .html file as output or Publish to the web.
Choose an address where to save the file and then open it with your Internet Explorer (Mozilla, Safari, Chrome).
Now you will be able to right click on the images and save them.
