Change logo for chat

HI,

Great plug-in. Just wondering whether I can change the logo that appears next to the chat fields. I was able to change the general logo that appears at the top of the Support field (via General – Logos), but that does not seem to alter the logo that is displayed when I chat with someone.

When I click View Image Info, I get a “gravatar” location (https://www.gravatar.com/avatar….” – can I change that?
