Ques: Your have a PowerPoint presentation (PPT or PPS) that contains lot of pictures embedded in the slides. Is there an easy method to save these images out of the presentation ?

As an example, let's take this [PPS 1.8 MB] PowerPoint presentation which contains unseen aerial photographs of the World Trade Center captured by a military chopper on 9-11.

To extract pictures from the PPT slideshow, all you have to do is export the Powerpoint Presentation as an HTML web page. [File -> Save As -> Select .html from the File Format drop down]

PowerPoint will automatically extract every picture embedded in the PPT file and save it to the local folder. The same technique is also used to extract sound from presentations.

If you want to look at the final result, here's an online photo gallery created from the above PPT file using Powerpoint and Picasa Templates. Total time taken is less than 30 seconds. [Image copyrights unknown]
