Here is how it was set:

mv image.png _image.png
pngcrush -force -text b "Author" "Guillaume Weexsteen <gui.mail@wanadoo.fr>" \
                -text b "Copyright" "2001 Guillaume Weexsteen" \
		-text b "Licence" "Those cards are under licence GPL v2 or later, and part of the cardpic project. See http://www.nongnu.org/cardpics/" \
