Issue with lb build.

I have an Issue with lb build.
Please help with telling me how to replace the stock Debian 800 x 75 Install banner with a different banner during the lb build.
Normally I simply look in /usr/share/docs for example scripts, then I know what to do and where to put them in config before
I run lb build.
But Debian 8 has no example scripts and the normal directory for this banner no longer exists either.
The Debian Live Build docs for 8.0 do not provide any information either.
Thank you so very much
John
