Untested, but illustrative?
function kButtonInit() {
var inputs = document.getElementsByTagName('img');
function addClicker(elm) {
addEvent(elm,"click",function () {kButtonBool.call(elm)});
}
for (var y=0; y<inputs.length; y++)
if (inputs[y].className == "kbutbool")
addClicker(inputs[y]);
}
(The "call" method of Function objects takes as its first argument
the object to be treated as "this" within the method.)
