1st. you need an ImageLabel inside a screengui.

2nd. you set the imagelabel's image with a localscript as shown below.

ScreenGuiWithImageLabel.Image = "http://www.roblox.com/thumbs/avatar.ashx?x=352&y=352&format=png&username="..game.Players.LocalPlayer.Name

This will set the imagelabel's image to the LocalPlayer's avatar picture. use a localscript for this.

Note: change "ScreenGuiWithImageLabel" to the imagelabel you want.
