How to change News Pro Background Image

I am trying to locate the image but I am unable to. there is no such image in demo/images folder. Checked other folders too but no luck.

How this background image is set exactly ?

Hi,
room photo from demo, from "News" section is here:
templates/gk_university/images/parallax_bg.jpg
We used: 1800px × 1200px JPG

I am using joomla, I dont have these folders. I have images/demo

Can you tell me where this file is located or set in joomla environment. ?

Got it,
Image has to be changed from server ( I am using Cpanel).

>File manager
>public_html/templates/gk_university/images
>We need to replace the image named parallax_bg (1800*1200)

I dont know why this configuration can't be designed to be changed from joomla interface ?

Thanks.

Read my first post in our second topic, not here,
but I will put here some extra info/tips

background image "Student sitting" from Demo
was definied here
gk_university\css\template.css

body {
background: #fff url('../images/bg.jpg') no-repeat center top;

it means that this image can be changes or here in that css file
or using a css line which will override our code
or by just replacing a image

sure in some other templates I saw a option to replace bg image from template settings panel, but not here, sorry.
