OK, I changed the snippet above, with the snippet below,...and it fixed it.

input.greenbox {
	background:url({vb:stylevar imgdir_misc}/tick.png) {vb:stylevar right} center no-repeat;
         background-color:#ffffff;
}

input.redbox {
	background:url({vb:stylevar imgdir_misc}/cross.png) {vb:stylevar right} center no-repeat;
         background-color:#ffffff;
}
