You can download some cool portraits from
Havak's Portraits and Sounds.
To use them, just create a folder named 'portraits' in your IWD main folder and copy the portraits there. Then in the game, when you create a character, select 'custom' from the portrait menu and select the port you want.
To change an existing character's port, go to the record-screen, click customize, and then appearance.
