The following very simple tutorial describes how to change the logo in RoundCube.
Made in seconds.

The guide is written for the operation of the directadmin panel, but it will easily work on servers without this panel.

We go to the directory of our roundcube:

cd /var/www/html/roundcube/config/

And we edit the file:

config.inc.php

nano config.inc.php

For servers without directadmin the location may be different.

We add a line at the very bottom:

$config['skin_logo'] = 'url of our picture';

We replace the url of our image with your reference to the image.
