Difficulty displaying image in new sidebox module

[Goshawk]

Hi all,
I am trying to build a template sidebox that can be used to add several social style websites and personal blogs, that can be styled to suit different image sizes and layouts inside the sidebox.

I need to display an image that links to the site:

<a href="social_site_url/social_site_ID" target="_blank" title=""><img src="social_site.jpg" width="" height="" alt="" id="" /></a>

The image is located in templates/MY_TEMPLATE/images
My coding of both the <a href=""> and the <img src=""> are not correct.
Where did I go wrong?

tpl_social_sidebox.php:

<?php
  $content = '';
  $content .= '<div id="' . str_replace('_', '-', $box_id . 'Content') . '" class="sideBoxContent" id="socialSidebox">';
  $content .= ?>'<a href="<?php FACEBOOK_URL . YOUR_FACEBOOK_NAME ?>"  target="_blank" title="<?php FACEBOOK_TITLE ?>"><img src="<?php ($template->get_template_dir(DIR_WS_TEMPLATE, $current_page_base,'images'), FACEBOOK_IMAGE_NAME ?>"  width='<?php FACEBOOK_IMAGE_WIDTH ?>' height='<?php  FACEBOOK_IMAGE_HEIGHT ?>' alt='<?php FACEBOOK_ALT ?>' id='socialImages')" /></a>';
<?php
  $content .= '</div>';
?>

Any help greatly appreciated,
