[Typo3] Drop-down sitemap - cannot find where media/bullets/blackclear.gif is defined

[W van Bruggen]

Hello list,

I'm trying to customize the look of the drop-down sitemap. For the
most part it's done; the second and third level bullets are customized
as well as the used colors. But i just can't find where
media/bullets/blackclear.gif (the little vertical dots) can be found
to be able to customize it..

I've searched with the object-browser but the value isn't listed
there. Is it hard-coded in the plugin ? That would be nasty if i'd
choose to use it in a different site (with..duuh..different colors :P)

Anyone have any idea where i can find it ?

greets,
Wietse van Bruggen
