adding a background image into hot news

I want to add an image in the background of each page in hot news in order to frame the page (as in Corporate template, how would I do this?

Can you explain better?

if you look at the tennis template is has this image in the background: I want to insert this kind of background image into the hot news portal template so the centered box is sitting opn an image background - at the moment the only thing I can do is change the templates background color. See attached image to get an idea of what I mean. Thanks

In tennis template we have this css for it:

you can add definition like that at bottom of template_css.css
You can use that exact css just change image url

Thanks for your response. Before I saw your response I used sparky framawork style designer to turn on the background image and then I uploaded an image and that worked. The only issue I have now is that the container background colour is showing around the edges of the logo.png image and I cant work out how to enlarge the image or reduce the logo container to get rid of the colour.Also I would like to change the colour of the logo bar or make it transparent - any idea how I could do that? your help on this is much appreciated. Please see image attached to show what I mean.
