Can I hide broken images?

[BlinD]

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:\[code\]//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;\[/code\]HTML:\[code\]<!--here is the HTML markup--><div id="inner_content_right"> <img src="http://stackoverflow.com/questions/3545132/<?php echo $side; ?>" /></div>\[/code\]CSS:\[code\]#inner_content_right { background: url(images/Layout_3_other_06_backup.jpg) no-repeat; width: 259px; height: 691px; float: right; position: relative; bottom: 28px;}\[/code\]Thanx in advance!
