NEOBLEEDER'S PROFILE

I'm a newbie with all RPGMAKER (I'm using RPGMAKERXP RIGHT NOW) All I know is how to make/edit simple maps and events. I don't even know how to animate the battle scenes.
But right now I would like to know how to put an image in the left or right side of the chat bar when a character is talking/chattingconversing with another charater???
Please, help would be appreciated.....
