One final question. What steps did the author of this file use to insert the background image this way so it wasn't accessible? I ask becasue I can see where this could be useful when you want to "lock" the image.
Right click your slide, choose format background, choose the picture fill radio button, browse to your picture, select it, click Insert. Then in the dialog, click Close.
