i´m using the html disclaimer and would like to add at least a custom image, but also some custom css code.
Neither the image nor the css code will be loaded.

Here is the code

        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1.0"/>
        <link rel="stylesheet" href="css/signatur.css" />
        <img src="img/logo.png">
        <p>Address line</p>
        <p>Address line 2</p>
        <p>20457 City</p>
        <p>Mail:&nbsp;<a href="mailto:mail@example.com">mail@example.com</a>&nbsp;</p>
        <p>Tel: &nbsp;<a href="tel:123456789" title="123456789">123456789</a>&nbsp;</p>
        <p>Web:&nbsp; <a href="somelink ">www.example.com&nbsp;</a>&nbsp;</p>
        <p><a href="https://www.example.com/" target="_blank">Wir freuen uns auf Ihr Feedback!</a></p>


The image is located in a folder named “img” within the /etc/kopano/disclaimers folder and the css file in the same path but “css” folder.

All the textual parts of the disclaimer are working.

Hope that anybody can help me out.
