Exactly my experience. All of the PageMaker files we converted for an
online version of our Resource Guide were significantly smaller as Acrobat
files. Acrobat's Distiller allows you to specify the level of compression
on color images, gray-scale images, and monochrome images. Perhaps this is
why experiences differ.

Check the DISTILLER menu for "Job Options." My settings are:

Color images:
Down Sample to 72 dpi
Compression: JPEG Medium
Gray Scale:
Down Sample to 72 dpi
Compression: JPEG Medium
Monochrome:
Downsample to 300 DPI
Compression: CCITT Group 4 (set by default)
