Answer 1

You should nest the <Directory Id="ImageFolder"> under <Directory Id="INSTALLFOLDER">, like this:

<Directory Id="TARGETDIR" Name="SourceDir">   <Directory Id="ProgramFilesFolder">     <Directory Id="INSTALLFOLDER" Name="WWU">       <Directory Id="ImageFolder" Name="image"/>     </Directory>   </Directory>   <Directory Id="ProgramMenuFolder" Name="Programs">     <Directory Id="ProgramMenuDir" Name="WWU 1.0" />   </Directory>   <Directory Id="DesktopFolder" Name="Desktop" /> </Directory>  

Note also that if there's no component in that folder, the empty directory won't be created. In order for this to happen, you'll have to author a component with <CreateFolder> element in it.
