Hi Dave! I don't see a broker logo on your account but you can edit your Profile as follows:
1. Log into your Trulia account with your primary email address and password.
2. Hover your mouse indicator over your name in the top right hand corner of the page and click on "Profile" from the drop down menu that appears.
3. Click on the big orange button on the left side of the page that says "Edit Profile".
4. Click on the title (Email Addresses and Facebook Connect, Change Password, Personal Information, etc) for each section you would like to update. (profile photo can be uploaded with the link under the photo)
5. Be sure to save your changes at the bottom of each section when your update is complete.
If you have additional questions, please contact us at http://www.trulia.com/help/ask/ or call Customer Service at 1-888-466-3501.
