Or, for anyone who doesn't want to wade through 7 files of generated
code (Using glade for code generation is generally frowned upon; please
please please use libglade instead), I've got two examples here that
weigh in at under 40 lines apiece.

GTK 2.6 added gtk_button_set_image() which certainly covers the most
common simple cases of this. If you've got to be able to build against
an older version of gtk, or need more flexibility, a GtkButton is
actually a GtkBin, so you can pack whatever you want in there.

image.c shows that; I just make myself a GtkHBox, load it up with a
GtkImage and a GtkLabel, and pack it into a GtkButton.

image-since-26.c shows the simpler case if you've got access to
gtk_button_set_image() and are happy with its behavior.

main (int argc, char **argv)

   gchar *file;
   GtkWidget *image, *window, *button;

   if(argc > 1)
   {
      file = argv[1];
   } else {
      file = "foo.png";
   }

   window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
   g_signal_connect(window, "delete-event", G_CALLBACK(gtk_main_quit), NULL);

   button = gtk_button_new_with_label(file);
   g_signal_connect(button, "clicked", G_CALLBACK(gtk_main_quit), NULL);
   gtk_container_add(GTK_CONTAINER(window), button);

   image = gtk_image_new_from_file(file);
   gtk_button_set_image(GTK_BUTTON(button), image);


   gtk_widget_show_all(window);
