Thank you for the module. I use it to load a random image in a block.
Recently I tried it with Ajax Regions module and found a problem how to make a callback to trigger Ajax Block in ajax loaded region. And I got it working only when I made it this way:

Drupal.ajax_regions.after = function(link, response) {
   jQuery.getScript('/sites/all/modules/ajaxblocks/ajaxblocks.js');
}

But I don't think this is the right way, can you advice me the more proper one?
