The display picture on your Forum posts are images that generated from Wordpress accounts.
They're more commonly known as Gravatars. Since our Forum section is Gravatar-enabled, the images that appear are from Wordpress accounts.
To personalize your Forum post display picture, all you'd need to do is create a profile on Wordpress.com for Gravatar, and add an image.
This image will then appear on your existing and subsequent Forum posts. Click here to create it right away. Just fill in the details and follow the on-screen instructions.
While creating the Gravatar profile, be sure to use the email address that is associated with your HappyFox account(applicable to both staff and customers/contacts).
The same email address being used should also match case-sensitively.
