Maybe if you set the image with the set_image method,

image = gtk.Image()
image.set_from_stock (gtk.STOCK_ADD, gtk.ICON_SIZE_BUTTON)
button = gtk.Button()
button.set_image (image)

And when you want to change the image,

button.set_image (newImage)

If you can't use the set_image method, you'll have to keep a reference to the image you want to remove, remove it, add it to the container, and hide and show the button.
