Easy Dialog Editing
Firstly I have to say the new visual options available in NSIS 2 are awesome. To edit the dialog boxes easily during compiling you can add the following line to your script
!packhdr tempfil.exe 'c:\"Program Files"\reshacker\reshacker tempfil.exe'

This assumes of course that you have Resource Hacker http://www.users.on.net/johnson/resourcehacker/ and it is located in the stated directory. I hope this is of some help, if it hasn't already been posted.
