change titanium icons

[raidzero]

How do you change the icons on the right side of the expanded panels? I figured out how to remove icons from panels by editing CPRs, but does anyone know where the icons are stored? If I knew that it should be as simple as overwriting the files with my own, testing, and cabbing.. thanks!

edit: regediting reveals this:
(while investigating the clock icon)

HKLM\software\microsoft\chome\cclock\ICONPATHS with a value of 2051;2051

I can not see a file by the name of 2051, plus if that was the name of the file shouldn't it be a path? titanium weather icons are a full path...
