Using firebug:

.wgo_block .blockbody {    background: url("http://www.thetradersden.org/vb4_suite/images/gradients/gradient-greytowhite.png") repeat-x scroll 0 0 #FFFFFF;    border: 1px solid #C4C4C4;}

Quick search in templates:

.wgo_block .blockbody {
    border: {vb:stylevar secondarycontent_border};
    background: {vb:stylevar secondarycontent_background};
    _background-image: none;
}
