The following tidbit appeared in this post on the MacStudentDev blog. You can install a Disk Image preference pane by navigating in the Finder (Go -> Go to Folder) to this folder:
/System/Library/PrivateFrameworks/DiskImages.framework/Versions/A/Resources
Double-click on the DiskImages.prefPane and you can install it for yourself, or for all users.
[robg adds: Interestingly, this preferences pane is the actual Preferences screen from Disk Utility -- they're identical, and changes in one show up in the other. So if you like the fast access of the preferences pane, install it via this hint. Otherwise, just use Disk Utility. It's nice to see "Skip checksums" as an official option now instead of a defaults write modification.]
