However, from reading over your email, it sounds like the image border. If so, try the following css.

.rf_fronttext_widget .postimage-border {
border: #ff0000 4px solid;
width: 268px;
height: auto;
overflow: hidden;
display: inline-block;
background: #fff url(‘images/glass_small.png’) 50% 50% no-repeat;
}
