Custom Scroll Bar

1

I have worked a little with flash before, and a lot with Adobe Photoshop. I have made a nice background which I am using for my site, and have the buttons worked out and all. My problem at this point is the scrollbar that flash provides in there component UI looks horrid with the theme I have going. I really just want to have an arrow pointing down and one point up in order to scroll the dynamic text. I have created these images of up and down arrows in photoshop and just don’t know how to make them do what I want them to. Pease help!
