how to change the backgound into an image?

my site is https://www.thesbeauty.com. Now I change my mind and want to change the green backgound color outside the store into a backgound image. How should I edit the stylesheet?

body {
In your stylesheet.css find:

background: url(../images/your_image.gif)
}
images folder is in includes/templates/your_template/

}
images folder is in includes/templates/your_template/

Yes, I followed the advice and changed the code.

I use a classic painting as the backgound image. It looks like the backgound image only takes part of the whole painting. How can I use the whole painting as the backgound image?

the paining image is attached. the painting size is 1024 * 768 (is it too big??). The site is https://www.thesbeauty.com

I think you're asking how to get the image to display on the right side. You can use background-repeat:repeat;
