Div Tag Question For Positioning A Background Footer

[reflex84]

Hi,I am designing a website and I have tried to add a footer background to the website and its not positioning the way I want it to!If you go to www.testing123.co.za .. you will notice the fish / coral background at the bottom of the website. The background image only starts straight after the last table... whereas I want the image to start further up , half of the image behind the bottom of my webpage and half of the image below the last table I have (hope you understand what I mean?) ... Does anyone know what I must do?NOTE: I'm not very clued up with css and html code, so please be alaborate for me.Another things: The image I want to try centre it,,,like I have done with my main background image at the top of the website (island + sea)Please help me - I would appreciate it!!dee.
