I made a guide on how to accomplish this here: http://forum.imgburn.com/index.php?showtopic=131
I followed this guide and it works great - only thing i have noticed is that Shrink calls up the first ImgBurn.exe file in the folder. In my case 1.0.0.2 or whatever, I save all my versions of the prog in one folder and maybe I need to keep just the latest one in there to stop this happening.
