The information in this article applies to:


 * Microsoft PowerPoint for Windows, versions 3.0, 4.0, 4.0a, and 4.0c

= 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.
