Rollover effects on Download button

[jeyjoo]

I have created my download and rollover buttons, but need to modify the following code to include mouseover, mousedown mouseout e.t.c

<img src=\"".get_gallery_image("download.gif")."\" border=\"0\" alt=\"\" />

Much appreciated

Seriously, anyone any ideas here. It is not a massive amount of coding...

... but will help contribute to a way better user experience.
