Hi Peggy, sorry I should make it a setting really, but edit
/skin/reboot/custom/header/dropdown_account.tpl
Replace...
Code:
{include file="customer/authbox_links.tpl" noavatar=false avatar=false dropdown=true}
With...
Code:
{include file="customer/authbox_links.tpl" noavatar=true avatar=false dropdown=true}
If you use noavatar=false avatar=true, it uses
Gravatars for the profile icon.
