All you should have to do is connect the signal "clicked" to the button in
question and change the image and execute the code on the callback function.

Assuming you use the same method that glade does to create a button with an
image this is how you would probably do it:

        mybutton = gtk_button_new ();
        gtk_widget_show (mybutton);
        gtk_container_add (GTK_CONTAINER (mywindow), mybutton);
        gtk_button_set_relief (GTK_BUTTON (mybutton), GTK_RELIEF_NONE);

        myalignment = gtk_alignment_new (0.5, 0.5, 0, 0);
        gtk_widget_show (myalignment);
        gtk_container_add (GTK_CONTAINER (mybutton), myalignment);

        myhbox = gtk_hbox_new (FALSE, 2);
        gtk_widget_show (myhbox);
        gtk_container_add (GTK_CONTAINER (myalignment), myhbox);

        /* myimage = gtk_image_new_from_stock ("gtk-goto-bottom",
GTK_ICON_SIZE_BUTTON); */ 
        myimage = gtk_image_new (...);  
        gtk_widget_show (myimage);
        gtk_box_pack_start (GTK_BOX (myhbox), myimage, FALSE, FALSE, 0);

        mylabel = gtk_label_new_with_mnemonic (_("some text"));
        gtk_widget_show (mylabel);
        gtk_box_pack_start (GTK_BOX (myhbox), mylabel, FALSE, FALSE, 0);
        gtk_label_set_justify (GTK_LABEL (mylabel), GTK_JUSTIFY_LEFT);

        /* connect signals */
        gtk_signal_connect (GTK_OBJECT (mybutton), "clicked",
                      GTK_SIGNAL_FUNC (on_mybutton_clicked),
                          NULL);        
        .
        .
        .

        void on_mybutton_clicked(GtkButton *button, gpointer user_data)
        {
                /* change the image */
                gtk_image_set_from_file (myimage, "somefile.xpm");


                /* do some code */
        }
