I don't want to spam my personal facebook with pictures of myself, so I may just make a different Tinder assigned to a fake facebook with a bunch of my pictures. Easier that way.
That's what I did. I never use my main profile so suddenly flooding it with photos would probably arouse questions, lol. Plus I remember reading that Tinder used to tell you what friends used the app(think they got rid of this) and I have no intentions of accidentally discovering my great aunt is using this to get laid.
You can add folders/photos onto facebook and make them only visible to yourself. You can then use these photos on tinder.
