Remove Blue Banner In Email Templates

Hello,

You have to edit your required email, in the Html part you have to remove the "<img>" with the Url "/media/com_hikashop/images/icons/icon-48-order.png"

This will do the trick.

Hi,

Once you're editing an email via the menu System>Emails, you have the HTML version where you can find the HTML code of the email. With old emails of HikaShop, all the HTML code was there including the header img tag.
However, since HikaShop 3.0.0, emails now have templates:
monosnap.com/file/1l9OugV8qAKssVfAbHrIXObauAGHZa
So the header and footer of the email are in the template file, not the HTML version of the email.
That way, if you modify the header of the default template, it will change for all the emails using the default template.
So, for the change you want to do, it's the default template that you want to edit with the edit icon next to the template selector dropdown.

Hello,

That's right. Core image will be re-installed with HikaShop packages. So you have to create a new image if you want to be sure to keep your customization.
You can place your images in the same folder (or in a sibling) ; the Joomla update system do not delete the content of folder during updates, just copy all files.

Hi,

That's right. When you modify the HTML/templates of emails via the interface provided by HikaShop, the changes are saved as overrides and thus you don't loose them when you update Hikashop.
