You want other peoples Portraits from the portrait thread? - Download them and put em in the portrait folder of NWN
Or you want a custom portrait for your character? - Then get yourself a good one. If you get it from NWNvault or someplace they are usually the right size. Just drop em in yer portrait folder again and choose the pic when creating your char.
If you find another cool pic you want to use in a diffrent format you would need to make it NWN compatible.
I forget the sizes again, best to download a ready portrait and then replace the image with your image in a grafix program. If you need help with that jes ask, i'm sure we can help convert it.
Cheers
