What's the best jQuery “click a thumbnail and change the main image” module?

Question

Here\'s what I have (all generated dynamically, if that makes a difference) :

• A list of images
• A caption for each image
• A thumbnail for each imag

Answer 1

Most of the answers here are like shooting a fly with a canon !!

$('#thumbs img').click(function(){
    $('#largeImage').attr('src',$(this).attr('src').replace('thumb','large'));
    $('#description').html($(this).attr('alt'));
});

this is all you need .. 4 lines of code .
