My child theme has been successfully installed. So, I guess my next step is to add the following snipped to line 27: <?php if(get_the_post_thumbnail()) { ?><figure class=”post-image”><?php the_post_thumbnail(‘large’,array(‘class’=>’img-responsive’)); ?></figure><?php } ?>.

Sorry, I’m self taught with knowledge gaps in my brain. I don’t even know what an SFTP client is.

Please send me a link to an article that will tell me how to add that PHP code snippet to my child theme.

Thank you.
