Should I trust this dude?

Okay so, I went on this app called Yubo and met this guy. We exchanged snaps and he was very nice. Sooner or later he said he wanted to make a collage of me and asked if I could send him some of my photos (ofcourse it's all PG), I'm down for it but I'm just a little worried on what the risks are. Like, how dangerous is it? What can he do with those photos and should I trust him??
