Change thumbnail size in functions.php
-
Hi!
In my empty child functions.php, I want to make a change to this code from the original functions.php:
set_post_thumbnail_size( 672, 372, true );
According to the codex, I am supposed to make a conditional clause:
if ( ! function_exists( 'theme_special_nav' ) ) { function theme_special_nav() { // Do something. } }
Unfortunately, I am a PHP beginner. Could someone help me phrase it?
Best regards
Leo
