Replace your player portrait with custom images.
The selected portrait is saved per character.
To change the portrait:
With the mouse pointer above your player portrait--use the Scroll Wheel to cycle through all the portraits--including the normal portrait.
To edit portraits:
Open the default images in a suitable image editor--replace the black circle with whatever you want to have as your portrait. Save the image. Use the command /reload in the game to load the updated images.
Make sure the image is saved in the same format (TGA, 32-bit) and that the area outside of the circle region remains transparent--otherwise you'll end up with a square portrait.
The portrait images are located in the \CustomPlayerPortrait\Portraits folder.
See Usage.txt under \CustomPlayerPortrait\About for more information--and learn how to bump up the number of portraits this AddOn can handle.
