Hi.
I tray add to pdf invoice my logo. For this purpose in the file plugins/hikashop/attachinvoice/attachinvoice/invoice.php I add the HTML tag of my logo image: but it doesn't work (see att).
Is this method still right? If yes, where exactly in the file should I embed this html?

Hello,

You can't use URL for images ; you need to use absolute path.

Regards,

Thanks,
With absolute path works good.
