Quick image edit

Hi, could someone edit the attached image (its the multiboard up/down arrow bit). What I need is to make the normal black surround bit transparent, so its just the blue button. I did this myself, but it turned out retarded ingame, so could you import it into the game interface and check?
In return for this you will of course have my eternal thanks :o or if you want some points when the system is back running.

Anyone willing to help? Its a really quick job
