Hi,

I would like to choose the large size for the featured image, because I put a watermark on the large size.

My full size is 725x1088 and my large size is 700x1050, but even though I change the size of penci full thumb in functions.php to :

add_image_size( 'penci-full-thumb', 700, 1050, true );

and insert a line:

set_post_thumbnail_size( 700, 1050 ); // 700 pixels wide by 1050 pixels tall, resize mode

the full featured image is always being displayed.

Is there somewhere in the theme's settings something like this:

https://slocumthemes.com/2014/05/adjust-set-size-featured-image-size-wordpress/#themes

so I can change the size of the featured image, or do I have to insert or change something else in the functions.php file?

Best regards,

Panos
