Something small I just found out you could do is you can put any picture you want as your profile picture (hit f2 to access) by:
1. Take the image you want to use and open it in a image modifying program (I just use paint for ease)
2. Resize the image to exactly 414 x 678 pixels and it must be saved as a .jpg
3. Place the image inside the BnS screenshot folder (Usually located under C:\Users\[Your Username]\Pictures\BnS\CharacterShot
4. Hit "Take a picture" on the UI and select the image
5. Afterwards, hit the refresh button on the top of the UI and it should update!
