Link and Embed in 2003

Using the InsertPictureFrom File comand we can use either the 'insert' or
'link to file' command to insert a picture. During our development we prefer
to link pictures then when completed save the .ppt with all pictures embedded.

1. When pictures are in slides during design is it possible to tell if the
picture is linked or embedded?

2. Is there a way to embed any/all linked pictures when the slide
presentation is completed without going to each slide and reinserting the
picture as 'insert'

Cheers!
