sure sulasno, change in the code both 'right' to 'left'
eg.
Code:
.signature a {
margin: 0px;
padding-left: 15px;
background-image: url('/images/link1.gif');
background-position:left center;
background-repeat: no-repeat;
}
.postcontent a {
margin: 0px;
padding-left: 15px;
background-image: url('/images/link1.gif');
background-position:left center;
background-repeat: no-repeat;
}
