I did some googling and figured I'm probably experiencing so called "event bubbling" that I've never heard of but are not surprised by it's existance. I want it to fire only once and I'm wondering how to fix this.

Basically, I have this small code snippet:

$('.bggallery_images').click(function () {      
    alert('test');      
});

This is supposed to fire once from a php snippet that basically adds an image of each image from a specific folder. It then outputs an echo string where each image has the class of "bggallery_images".

PHP snippet looks like this:

                    <?php
                    $dirname = "img";
                    $images = scandir($dirname);
                    $ignore = Array(".", "..");
                    foreach($images as $file)
                        {
                        if(!in_array($file, $ignore))
                            {                                                           
                                echo "<img class=\"bggallery_images\" src=\"$dirname/$file\" />";                                                               
                            };
                        }  
                    ?>  

This all generates the html markup that looks like this for each image:

<img src="img/WhitePattern6.gif" class="bggallery_images">

What is happening here?

Here's the rendered output from FireBug:
