Related posts no-image-half-landscape.png

I am using an older theme that I’ve tweaked a lot and have it coded to display related posts.

It refers to a no-image half-landscape.png and of course the theme does not have a file by that name. Here’s a snippet.

echo('<img src="'.get_template_directory_uri().'/images/no-image-half-landscape.png" alt="no image" />');

I am om a VPS and getting errors in my log
File does not exist: /home/user/mysite.com/wp-content/themes/Gopress/images/no-image-half-landscape.png

Any idea on how to resolve.
