Suddenly, on my mom's iMac (running Tiger), whenever she gets an email from me, my iChat photo appears over on the right side of the header of the email. I have no idea where there might be a setting to switch this functionality on/off. Anyone know about this? I'm fairly certain it's a setting on her computer, and not on mine. It allows her to see someone's iChat photo in an email that they send her. I've looked in Mail, and iChat, but can't find a setting that suggests it controls this function.
