When configuring newsletters, you may want to use your own custom images and photos.
When you create your newsletter content, you can use HTML tags to display images within the message body. If you're unfamiliar with HTML, you can quickly upload and embed image files into your message using the Easy Editor on your store's newsletter configuration page.
