How to make a large wall map?

Found an article on the subject:
but a simple save/edit the html in this case didn't work, hands curves, or the code is changed.
Maybe you know how to Yandex (like most) or other services to make your big map on the wall?
30000х18000 pixels, for example.
Thank you.

Regarding the article - was also a problem. Fixed the last known good code for it. Change the center of the map, choose the scale and the desired resolution.
For example, put 1000x1000px.
What screen shot do not remember, like Full Page Screen Capture, I will have to try different.
<!DOCTYPE html>
the <head>
<title>Yandex Map</title>
<meta charset="utf-8">
<script src=""></script>
the <script>
function init () {
var myMap = new ymaps.Map("map", {
center: [51.651080, 39.221870], 
zoom: 15
<body style="margin:0;">
<div id="map" style="width:1000px; height:1000px"></div>
