As you can see below, your new email has been assigned to your Gravatar account. It should appear below like I have demonstrated below.

We still need to associate an image with the newly added email.

You can see below I have 2 images uploaded to my Gravatar account. One is associated with my Primary address, so I decided to use the other image for my new email account. (you can associate the same image with many emails if you wish to).

My new email now has an image associated with it. (shown below)

Also, make sure your images are G Rated so they will appear uninterrupted when you comment.

This is the solution for the commonly asked question Why isn't my Gravatar profile image showing when I comment?
