JS代码要注意viewList: ['qzone', 'tsina', 'weixin', 'tqq']， "bdselectMiniList": ['qzone', 'tsina', 'weixin', 'tqq']两个地方，要对应html中的data-cmd属性

 "bdSize": 32; viewSize: '32',两个地方需要改为16，32，64的尺寸，图标也需要制作为16，32，64的尺寸

.F_share .bdsharebuttonbox a {width: 32px; height: 32px; display: inline-block; margin: 0px 5px;}
.F_share .bdsharebuttonbox .bds_qzone {background: url(../images/qz.png) no-repeat top center;}
.F_share .bdsharebuttonbox .bds_tsina {background: url(../images/weibo1.png) no-repeat top center;}
.F_share .bdsharebuttonbox .bds_weixin {background: url(../images/weixin.png) no-repeat top center;}
.F_share .bdsharebuttonbox .bds_tqq {background: url(../images/weibo2.png) no-repeat top center;}
