If you want to display your (or your service agents) profile photo on the Customer Portal, remember to set it as visible to anyone. Otherwise, the portal will show the initials of the name and surname instead of a photo.
Go to Atlassian Account > Profile and visibility. Next to the profile photo under the question Who can see your profile photo?, select Anyone. You can read more about account settings in the Atlassian Documentation.
