systray icon style

["opax gm gmail com" <opax gm gmail com>]

hello!

I m build a new theme for gnome. but i got a problem.
is it possible to choose which picture whould be used in the systray.
in fact i d like to use different style for those icons.
Is it possible to choose in which directoriy the applications search the
icon for their systray presence?

thanks!
