The quake-UK.php doesn't produce any image links.. it's output ends with the "All rights Reserved."
That second link is likely on the including page.
Yep.. in wxquakeUK.php, it's <p style="align: center"><a href="http://www.earthquakes.bgs.ac.uk/"><img src="http://www.earthquakes.bgs.ac.uk/uk.jpg.0" alt="Recent Earthquake Events"
width="338" height="520" style="border: none;"/></a></p>
they are producing the strangely named image, but only in http. So if your site is https, it won't display due to browser rules about mixed https/http content.
