You can use something like this

#include <gconf.h>

gconf_client_unset (client, "desktop/gnome/background/picture_filename",
NULL);
gconf_client_set_string (client,
"desktop/gnome/background/picture_filename", filename, NULL);

Of from shell 
gconftool-2 --unset desktop/gnome/background/picture_filename
gconftool-2 --set desktop/gnome/background/picture_filename $filename


Note that first you should unset gconf key and then set it again,
otherwise, if
filename won't change, the picture won't be reloaded. But if filename
changes, you can just set key to right value.
