It's not necessary to place portraits in a hak. It can also be accomplished by someone acting as the point of contact and taking the responsibility of compiling and maintaining the portrait files for Thay in a way that all those portraits can be easily downloaded. Like putting all of them into a .zip file and then sharing it publicly on Skydrive or some other file sharing site. Provide the link to the .zip somewhere on the forums here, and then each person interested in having them can download it and extract the files to their C:\NeverwinterNights\NWN\Portraits folder (which may need to be created if you don't have one).
