When I changed logo.png in image directory , How much time it takes to get loaded on the forum . I changed the logo.png and opened the forum but no change . What Should I do ? Should I delete the white_logo.png or anything else ?

you have to refresh your browser cache. (try pressing CTRL + F5 keys a couple of times on forum index page)
