This could be possible with VBA. The following line of code adds a picture
to the slide number stored in the variable slideNumber with the file name
stored in the variable "pixFile":
ActivePresentation.Slides(slideNumber).Shapes.AddPicture _
FileName:=pixFile, LinkToFile:=msoFalse, SaveWithDocument:=msoTrue, _
Left:=220, Top:=220
The variable pixFile could contain a file name (to just use the current
folder) or a complete path name.
