XF 1.2 Centering Staff Banner Image

Hey All,

I just changed the default staff banner to an image I created. It changed properly, but it is not centered with the postbit.
Picture to show what it looks like.

The code I used for this is the code from @Jefferson Filho here: http://xenforo.com/community/resources/user-ranks-with-images.2054/

Or here it is again:
.userBanner.bannerStaff {
background: url("special/staff.png") no-repeat;
height: 24px;
width: 91px;
text-indent: -10000em;
display: block;
