Adding images to package source

["Tille, Andreas" <TilleA@rki.de>]

Hello,

I wanted to add a PNG image to a package source (to provide an icon
for a program in /usr/share/pixmaps).  This wokrs for XPM files because
they are plain textfiles.  Unfortunately I get for a PNG:

dpkg-source: cannot represent change to debian/trophy.png: binary file contents changed
...
dpkg-source: building trophy in trophy_1.0.6-1.dsc
dpkg-source: unrepresentable changes to source
debuild: fatal error at line 322:
dpkg-buildpackage failed!

How to solve this?

Kind regards

        Andreas.
