Screencaps not showing?

I added a bunch of 퀴즈 질문 a few days 이전 with movie screencaps attached to them, but now it seems they got deleted. So I'm just wondering if anyone knows why, 또는 if anyone answered some of those questions, were 당신 able to see the screencaps 또는 not?

I was able to see them, so I don't understand why other people weren't able to... I'm so confused :/
