Changing an image.

Question

hi.
i have a JLabel with an image, like so:
JLabel label = new JLabel("", m_image1, SwingConstants.TRAILING);i want to change that image to another image with the same dimensions.
this:
label.setIcon(m_image2);doesn't work...
even if i add label.repaint() nothing changes.
how do i make it change?
thanks!
