blue box around thumbnail

[davy_yg]

Hello, I am trying to have this lightbox thumbnail:

lightbox thumbnail

and I find a blue box around it I wonder why.

This is all I have for jquery lightbox css:

#jquery-overlay {
    position: absolute;
    top: 0;
    left: 0;
    z-index: 90;
    width: 100%;
    height: 500px;
}
#jquery-lightbox {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    z-index: 100;
    text-align: center;
    line-height: 0;
}
#jquery-lightbox a img { border: none; }
#lightbox-container-image-box {
    position: relative;
    /* white */
    background-color: white;
    width: 250px;
    height: 250px;
    margin: 0 auto;
}
#lightbox-container-image { padding: 10px; }
#lightbox-loading {
    position: absolute;
    top: 40%;
    left: 0%;
    height: 25%;
    width: 100%;
    text-align: center;
    line-height: 0;
}
#lightbox-nav {
    position: absolute;
    top: 0;
    left: 0;
    height: 100%;
    width: 100%;
    z-index: 10;
}
#lightbox-container-image-box > #lightbox-nav { left: 0; }
#lightbox-nav a { outline: none;}
#lightbox-nav-btnPrev, #lightbox-nav-btnNext {
    width: 49%;
    height: 100%;
    zoom: 1;
    display: block;
}
#lightbox-nav-btnPrev { 
    left: 0; 
    float: left;
}
#lightbox-nav-btnNext { 
    right: 0; 
    float: right;
}
#lightbox-container-image-data-box {
    font: 10px Verdana, Helvetica, sans-serif;
    /* white */
    background-color: white;
    margin: 0 auto;
    line-height: 1.4em;
    overflow: auto;
    width: 100%;
    padding: 0 10px 0;
}
#lightbox-container-image-data {
    padding: 0 10px;
    /* white old: #666*/ 
    color: #666; 
}
#lightbox-container-image-data #lightbox-image-details { 
    width: 70%; 
    float: left; 
    text-align: left; 
}   
#lightbox-image-details-caption { font-weight: bold; }
#lightbox-image-details-currentNumber {
    display: block; 
    clear: left; 
    padding-bottom: 1.0em;  
}           
#lightbox-secNav-btnClose {
    width: 66px; 
    float: right;
    padding-bottom: 0.7em;  
}

#jquery-lightbox a { border: none; }

I just did. and the dark blue line still there around the thumbnail.
