Lots of ways.  In 10.4 at least, move the files to be distributed into a 
folder with the name of the volume to be created, launch Disk Utility 
(/Applications/Utilities/Disk Utility.app), then drop the folder onto 
the Disk Utility icon in the dock.  A "New Image From Folder" file 
dialog will appear with the correct name and with "compressed" selected 
as the default Image Format.

Or from a shell command line:

   hdiutil create -srcfolder /path/to/folder /path/to/new_image.dmg

The contents of images can be and are compressed by these methods.  See 
the hdiutil man page for more gory details.

Again in 10.4, a very simple way is to create a two-step Automator 
workflow using the Get Specified Finder Items action and the Create Disk 
Image From Files action (available here):

<http://www.apple.com/downloads/macosx/automator/creatediskimagefromfiles
.html>

Then Save As Plug-in... for Finder and the new workflow should show up 
in the Finder's right click menu under the Automator submenu.
