Obvioulsly it was a stupid question....sorry for that.
question not, but reply 1 to me is

Himm, maybe we should put more info to forum intro:
This is not a commercial forum,
Win7PE SE is not a commercial project,
We are also not pc magazine etc.
We do not hire people as support posters to reply others,
All people around here have other works to do in real life,
So waiting a reply only for 4 hours is really a bad attitute.....
Anyway,
In addition to ChrisR advice

Win7PE SE already have \Components----->Additional Files
where you can easly add anything like imagex.exe
