PHP Image Link in template

I’m working with a template (http://www.lastkeyrealty.com/wordpress/portfolio-view/puerta-coralina/) and there’s a certain portion of the portfolio page on the right side that is text input only. The “click here” link on the right side I want to be an image instead of text. Here is the php code, is it a simple fix to change this to an image link instead of a text link?

if( !empty($portfolioURL) ) {
echo ‘

• ‘;
  echo ‘<strong class=”portfolio-meta-key”>’ . __(‘Rates & Additional Information:’, ‘framework’) . ”;
  echo “” . __(‘Click here’, ‘framework’) . ““;
  echo ‘

‘;
}
