changing installer images

[Michael Anckaert <michael anckaert pi be>]

Hello,
I'm trying to change the anaconda images, such as anacona_header.png and
such. I'm doing this by installing the anaconda-images-src rpm,
modifying it and rebuilding it. Yet rpmbuild seems to changes the images
back to the standard fedora images. I can't run a patch on the files
because rpmbuild complains that the patch contains "garbage". 
Any help?
Thx




Met vriendelijke groeten,
Kind regards,
