Scroll texture with white background

Hi guys, Can any body tell me how to get rid of the white edge of a texture? My case is I want to display to scroll for description in 2D guiNode of the game. I have the scroll texture (jpg) with the white background. How can I get rid of that background so the scroll is displayed pretty in my game. Thanks

Save it as an .png and remove the white background in GIMP for example. Be sure that you are using layer with alpha channel.

It works. thanks, bro. ^^
