How do I change which program Outlook uses to view pictures?

[Dave]

When I view pictures from my inbox, Macromedia Fireworks starts up. I would
like them to be opened with Picture and Fax Viewer to reduce load time. How
do I change this setting?

This is a Control Panel setting - not Office.
Go to Control Panel
Folder Options
File Types

Scroll down to the file type in question (.jpg, .gif, etc)
Click to highlight
Click 'Change'
Select the new program required to open file type
