Fluxbox SlackBuild and other question

Hi slakers! Can you suggest my URL to retrieve a fluxbox slackbuild?
I want to recompile in order to enable .png icons, official version (slack 14.2 x86-64) accept only pixmap files; this format show pixel at the border.

So my last question is: it's possible change triangle menu (rootmenu add on init file) with personal image menu?

Thanks
