Don't know about a slideshow, but this will open a single picture.

Start | Run |
rundll32.exe %SystemRoot%\System32\shimgvw.dll,ImageView_Fullsc reen
path-to-picture (or path-to-folder name)

There should be one space between
ImageView_Fullscreen
and
path-to-picture (or path-to-folder name)

path-to-folder name opens the first picture in the folder.

Hope this helps. Let us know.
