SUMMARY
=======
 
If you make a copy of a linked object or a slide that contains a linked
object, in PowerPoint for Windows, you do not get a copy of the link. This
means that if you use the Links dialog box to change the source of one of
the objects, the source is changed for all of the copies of the object
because they are all updated from the same link.
 
For efficiency, PowerPoint stores all external objects (links, embedded
objects, pictures, and so on) in a pool, which is associated with a
document, not a slide. If a copy is made and pasted within the same
document, the duplicate object is considered to be identical, and no second
copy is made.
 
Both copies refer to the same item in the pool. If one of these objects is
activated and then modified in its server, the objects become different.
For example, you will now see two linked objects listed in the Edit Links
dialog box.
 
This is done because the display formats (pictures) for objects can use
large amounts of memory and disk space. As a result, PowerPoint tries to
avoid duplication as much as possible. For example, let's say you want to
use the same photograph in several different slides (at different locations
in each slide and maybe scaled differently too). If that bitmap increases
the file size by 1 MB, and PowerPoint has to duplicate all of the data for
the photograph each time you use it in the presentation, the file will
become very large.
 
To avoid this problem, you can import the picture once and then copy the
picture from one slide into the other slides, where it will be used. Now
the file does not grow appreciably for each additional copy of the picture.
