FL Scrape Question

Hey Guys,
I need a quick tip!

I want to follow people based on "users who liked a picture".
So I put in 5 photos with about 10k likes. But i want to scrape 100 users each a pictures = 500 Users.
I dont want to scrape 500 from pic 1, I want to have 100 from pic 1, 100 from pic 2.

What do I need to do?

Thx
