Come to think of it, there's no need for the counter variable:
document.observe("dom:loaded", function() {
$('main').update('<img src="shared/images/ajax-loader.gif"
width="100" height="100" alt="Ajax Loader">');
var links = $$("div#thumbs a").each(function(link, i) {
new Element('img').observe("load",function() {
if (++i == links.size()) {
$('main').update('<img src="' + links[0] + '"
/>');
}
}).writeAttribute('src', link);
}).invoke('observe', 'click', function(event) {
event.preventDefault();
$('main').update('<img src="' + this.href + '" />');
});
});
