To insert an image in your email marketing campaigns, you will need to do the following:
In the email editor, drag the "Image" icon (it looks like a small picture with mountains on it) into your email. Look for the button called "Browse Server."
When you click this button, a new window will then open that will allow you to upload a file. Look for the button that says upload at the top. When you click on this icon, you'll see a button labeled "Choose File." Click on this icon to browse for your image. When you're finished browsing for your image, click on the "Upload Selected File" button. Double-click on the image to select it.
Now that you have double-clicked on the image, you will see its path in the URL box in the previous window called "Image Properties." Click on the ok button to apply the changes. Once you do this, you'll see the image appear in the message content.
