Background isn't displayed in browser

Hi guys,

So I've made my webpage in animate and looks great. But only on my computer. After uploading it on server the background image of my website isn't displayed, but rest is. Any ideas how to fix this?

I use this code to have full screen background:

<code>

sym.$("Stage").css({'background-image':'url("images/Background.png")',' background-repeat':'no-repeat','background-size':'cover'});

</code>

Thank you
