Batch image extraction from .ppt and .pps files...

[Merlin]

I thought you all needed a challenge this evening, so here's my second issue for tonight...

Over time I have accumulated a large number of .ppt and .pps files. Most of them are those chain email-type files.

Regardless, there are some really nice photos in some of them.

Individual extraction or screenshot-copying are not really an option due to the sheer number of files and images.

Google is not turning up much...

Is there an app' available that I can load these into and get images out of?

Thanks.
