News Background won't change

Hi,
First of all, congratulations for this beautiful template (Restaurant).
Everything worked fine, and I am really happy with it.
There is just one problem. I was able to customize and change everything I wanted, except one thing: the background from the "news" module won't change at all. I tried changing all of the images that were named as news_bg.jpg (or something like it) on every folder that had this image (I don't remember now, but it was placed only on the demo folder, wasn't it?!)
So, do you guys have any idea why it just won't change?
Again, congratulations, and thanks for the upcoming help!
Fernando

Could You please post an url to your site?
Could you please mark on a screenshot which image exactly would you like to change?

Hi,
The link is saladaquenada.com.br
The section of the image is right below the "testimonials"... the "events & blog" part - sorry, my mistake: not news but "events&blog".
In my site it is called as "novidades & dicas"
tks
