I am trying to create a sidebar for which I can specify the image in the back-end of my wordpress cms using custom fields, now I have gotten it to work, with just one little bug, if the user enters a invalid URL, the image link will display as broken and will not display, is there a way that I can hide the broken image icon perhaps?

I have a background image set for the parent DIV element so that if there is no image to display, the parent's background will.

here is the PHP code:

```
//here I get the 'side_image' custom field, which will contain the URL to the side image    
if (have_posts()) : 
         while (have_posts()) : the_post(); 
             $side = get_post_meta($post->ID, 'side_image', true); 
         endwhile;
 endif;

```

HTML:

```
<!--here is the HTML markup-->
<div id="inner_content_right">
    <img src="<?php echo $side; ?>" />
</div>

```

CSS:

```
#inner_content_right {
    background: url(images/Layout_3_other_06_backup.jpg) no-repeat;
    width: 259px;
    height: 691px;
    float: right;
    position: relative;
    bottom: 28px;
}

```

Thanx in advance!
