The information in this article applies to:
 
 - Microsoft PowerPoint for Windows, versions 3.0, 4.0, 4.0a, and 4.0c
 - Microsoft PowerPoint for Macintosh, version 3.0, 4.0
 ----------------------------------------------------------------------
 
SYMPTOMS
========
 
When you insert a bitmap (or paint-type) graphic image on Slide 1 of a
presentation, the presentation file size increases substantially.
 
CAUSE
=====
 
This behavior occurs because the contents of Slide 1 are saved twice; once
as Slide 1 and once as part of the presentation's header.
 
RESOLUTION
==========
 
If you insert the bitmap on Slide 2 and leave Slide 1 blank, the file size
will increase by much less.
 
MORE INFORMATION
================
 
In general, any bitmap graphic inserted into a presentation is converted to
a generic bitmap format that is used internally by PowerPoint. If the
bitmap is compressed to begin with, as many PCX- and TIFF-format bitmaps
are, the increase in the presentation size will be greater than the
original bitmap file size. Windows .bmp files do not have data compression.
