'Preview' will always be the default action for files with a 'perceived type' of 'image' unless you define the preview action for the filetype. If you do that, 'preview' will then be shown in the 'Edit File Type' dialog ('Folder Options' -> 'File Types' tab -> 'Advanced' button) and you can select a different action to be the default without losing all functionality of the Windows Picture and Fax Viewer (I like the print wizard, myself
.
If you copy all the text between the lines that follow and save it as a ..reg file, then right-click & select 'merge', the preview option will be visible in the 'Edit File Type' dialog for image files.
Hope this helps,
Keith
(This is based on the file extensions in my registry, which I think were all part of the XP install)
