Changing Image in "Guest User" Icon at login screen???

[seanjohn87]

Ok, I have a 2011 macbook pro running lion. I'm sure there are people who have noticed the guest user account that is not really a guest user account by now... For those that don't know its the one that only allows you to run safari on it and serves as a way for you to locate your mac in the event that it gets stolen. I think that could be useful and plan on keeping it at my login screen, but my question is

HOW do you change the picture inside the "Guest User" icon???

I have tried going into system pref already, and unlike the user account, I am unable to edit the picture..

Any effective solutions would be greatly appreciated

Try that one...

Also, you can make it a "real" Guest User Account in the System Preferences.
