strip()
function strip() {
for (var i=0;i<g_questions;i++) {
document.write("<img id='e"+i+"'>");
}
}

Notice that I have used e0, e1, ... for the id's since we have already used 0, 1, ... in the answers div.

So now we can write finale().

function finale() {
Hide('main');
Show('end');
for (var i=0;i<g_questions;i++) {
var el=document.getElementById('e'+i);
el.src=g_dir+'/'+g_used[i]+'.jpg';
}
}

Try it and you will spot a couple of issues.

First, the space where main is, remains. That is because it is still there, just not visible. We have to be more heavy-handed and do this:

function finale() {
var el=document.getElementById('main');
el.style.display='none';
Show('end');
...
}
