In your additional.css you have this:
Code:
.tcat {
background: url("images/styles/Movara/style/tcatBG.gif") repeat-x scroll left top rgba(0, 0, 0, 0);
border: 0 none;
clear: both;
color: #343b42;
float: left;
height: 47px;
margin-top: 8px;
width: 100%;
}
.tcatLeft {
background: url("images/styles/Movara/style/tcatLeft.gif") no-repeat scroll left top rgba(0, 0, 0, 0);
height: 47px;
}
So change the values for the background there.
