Everything is much easier! I just do support the specific site. ?? This can be done directly in the theme settings:
Theme Options – Header – Header Image + add your image

I asked my friend to help me with translation, as the online translator cannot do the correct translation and you probably didn’t understand what I wanted to say.
“Thank you very much for your quick reply!
Unfortunately your decision helped me just partially. Probably I didn’t explain properly what I needed. After I made changes in header.php file, the header and the description moved on the top of the web-site and are under the picture at the moment. But I need the header and the description to be on the picture, like a picture is a background image. I can suppose I should make some changes in style.css file, for example to add a background image with specifying the path to the picture. But I cannot get it as the picture becomes trimmed to the size of the original area of the site. Here is the screenshot where you can see what happened after I made changes to header.php file. I marked with red what I want to happen. Thanks a lot!”

Now Online modified file header.php:
<?php if ( ot_get_option('header-image') ): ?>
as you said.
File style.css unchanged.

I have three days trying to solve this problem.
If you do not modify the file header.php, as you said.
A change file style.css:

#header {
    background-image: url("https://kazaksbugra.ru/wp-content/uploads/2015/02/logo.gif");
    background-repeat: repeat;
}

The picture is inserted into the header. But it turns out the circumcision.

Yes of course. https://kazaksbugra.ru/

The first message is posted using an interpreter. Sorry, I do not know much English. Show in the picture. After modifying it so as in the figure. How to do that red?
