Are you looking for a tool that does this job for you without having powerpoint installed in your system?
You want to create a tool of your own?
Maybe you can do some research on the Windows/powerpoint component that does the convert of PPT to JPG and use that in your VBScript code. Let me also try to find that out, if any on the web.
Just surprised, if at all powerpoint can do that for you why do you want to do it on your own.;)
