User blog:Tanglefrost/dumb question i probably shouldn't have wasted a blog on, but oh well

Tangle has a question! Pay attention! c:

Okay, soooo

In people's fanfiction things I noticed they had black and white pictures for eliminated castaways. How do I make the pictures black and white? Do I have to go back on ton FYM and make an exact replica of the avatar and do it black and white, or is there another way?
