Went to their concert, but IDK how to get my pictures with the boys after the concert so tbh.

What the title pretty much say. I went to their concert recently in Auckland, New Zealand and gotten a free upgrades ticket. Since they didn't manned to sold out all of their tickets at all, so they decided to upgraded all of us tickets. So we can all be close and not space out at all. I then gotten upgraded from a none band to a band, where I could high five them and get pictures with him. But I didn't knew/ know what I was doing and stuff, as this was my first time going to their concert. Anyway. I'm a little bit confuse/ wondering how to get my photos from them now? as no one say/ tell me there, email and or on their ig account. So i'm hoping someone on here know how to get them and stuff. Thank you!
