NUK3MAN: That would be awesome if you would test that. My research tells me my install location is the problem. But I'll go ahead and install it in the default and see if that does anything. I'm seeing the portraits but they're showing up with the question mark. I've checked and there is nothing wrong with my pics.
Okay, just tested and have no issues. Slightly more detailed info:
Win7 Professional 64 bit installed on a 64 GB SSD (Drive 'C', of course).
I have the GOG version of BG installed on on a 1.5 TB HDD (drive 'E', my Games drive). Made a female Elf Ranger and selected a custom portrait and had no issues during the character creation process nor at the beginning of the game. I installed the game as Admin and have the Privilege Level set in the Compatibility tab to run as Admin as well.
Hope that helps narrow down the issue for you.
