To upload a new image, click the "Upload File" button.

Now you can choose 1 or up to 6 images to upload at a time. 

Be sure to format your images for web use, in the proper size for what you plan to use them for.  It is better to resize them outside of the application, and save as "web quality" so that you will not have large images that are difficult for customers to preview.  Inappropriate image file sizes may contribute to your e-mails going to spam.
