He conseguido adaptarlo a mi gusto excepto por una cosa.
Quisiera que la caja se cerrara al pulsar en ella, no solo al pulsar en el exterior.
Código:
var TINY={};
function T$(i){return document.getElementById(i)}
TINY.box=function(){
var p,m,b,fn,ic,iu,iw,ih,ia,f=0;
return{
show:function(c,u,w,h,a,t){
if(!f){
p=document.createElement('div'); p.id='tinybox';
m=document.createElement('div'); m.id='tinymask';
b=document.createElement('div'); b.id='tinycontent';
document.body.appendChild(m); document.body.appendChild(p); p.appendChild(b);
m.onclick=TINY.box.hide; window.onresize=TINY.box.resize; f=1
}
if(!a&&!u){
p.style.width=w?w+'px':'auto'; p.style.height=h?h+'px':'auto';
p.style.backgroundImage='none'; b.innerHTML=c
}else{

this.mask();
