Background position, margin-top?
background-image: url(/images/poster.png);
background-position: center;
background-position-y: 50px;
background-repeat: no-repeat;
If you mean you want the background image itself to be offset by 50 pixels from the top, like a background margin, then just switch out the top
for 50px
and you're set.
#thedivstatus {
background-image: url("imagestatus.gif");
background-position: right 50px;
background-repeat: no-repeat;
}
