you can also create another key for any icon you don't know where it is (sometimes the shortcuts just refer to the icon's picture instead of a png)
All I did to create whatever icon I wanted was to add a registry key that basically still keeps the shortcut pointing towards the original program but also assigns a png. to it so in a sense it redirects the shortcut to show your pmg while still pointing towards it's original target. If you are confused (shit I am confusing myself just writing this) then let me know and I can tell you exactly 1-2-3 how I did it. You'll never have to hunt around again... BTW I am thinking about releasing my first public ROM, I have been building mine and finally got everything that has ever bothered me worked out so I think in the next few days I will release it if there is any
interest. I'll post some pics ...
