alignment of background with images

Hi there,

I’m working on this site http://tarnishandtwine.com/ and while I set each image where I wanted it specifically (and it’s perfect on my computer) I’m worried about how the images will look in relationship to one another on different browsers/computers.

Can anyone how to make sure this will work?

Thanks!

body.custom-background {
background-attachment: fixed;
background-image: url(‘http://tarnishandtwine.files.wordpress.com/2013/02/535×535-tarnish-and-twine-background2.png’);
background-position: 443px, 30px;
background-repeat: no-repeat;
}

And I’ve placed each image exactly where I wanted it like this:

<img class=”alignnone wp-image-190″ alt=”twitterlinkhome” src=”http://tarnishandtwine.files.wordpress.com/2012/11/twitterlinkhome.png&#8221; width=”35″ height=”35″ />

<img class=”alignnone size-full wp-image-195″ alt=”facebooklinkhome” src=”http://tarnishandtwine.files.wordpress.com/2012/11/facebooklinkhome.png&#8221; width=”35″ height=”35″ />

<img class=”alignnone size-full wp-image-202″ alt=”instagramlinkhome” src=”http://tarnishandtwine.files.wordpress.com/2012/11/instagramlinkhome.png&#8221; width=”35″ height=”35″ />
