Hello I'm pretty new and I would like to ask a question. Where do i find Portraits?

Hi, Twenty_seven, and welcome!  To assign a portrait to your character in a game, click Character Details, and then click Change Portrait to be taken to the Portraits screen.

For more about portraits, you can go here in the FAQs:  http://portraits.rpol.net/help/?t=faqs

Note that portraits can only be used in games, not on the general public forums.
