you can make all sorts of collages by cropping, pasting, cutting, and drawing on pics and stickers adding videos, gifs, or whatever to make cool, cute collages that others can see:)

contests are collages people make to get their followers to make cool collages in response in exchange for likes, shoutouts, or whatever the person decides. a lot of pic collagers make them to encourage people to follow them and people often enter for the rewards:) hope this helps!!

thanks
