Change the Building background in the header

Hey There,
I'm trying to modify the background image in the header, the semi-transparent images of buildings. I can't seem to find where I can make the modifications, any help would be appreciated.

I would like to know this too, any help would be great!

Hello.

If you wanna change the Buildings semi-transparent image that Drawn from the top to bottom of the slider please follow this solution:

Find ->

YourThemeDirectory/Images

YourThemeDiretory in this solution is Architecture.

Find ->

back-top.jpg

change it or replace your favorite background to this directory.

Just remember to check your dimension's background and the original background for better view of your website.

To remove this background please follow this solution:

Find->

YourThemeDirectory

that you can find it in wp-content\themes\Architecture\

open the Style.css with notepad or some editor,
Find this code->

#all

or

url("images/back-top.jpg")

and remove all objects between { and } tag in the front of #All or simply remove this row:

#all { background: url("images/back-top.jpg") no-repeat scroll center top transparent; }

Probably it's the code or maybe with more whitespaces :D

Hope Work,
Have fun!
