pictures

Q: In our class some boys took an exam paper from our teachers laptop when he was out and they took pictures of it and maybe that is the same paper which the teacher is going to give us for the final exam. They did a wrong thing. I didn't have the courage to stop them. What should I do now? If I complain then all the boys will be saying bad words to me and they will mock me etc. But I dont need sin. And maybe if they dont get that paper then they will fail and maybe need to repeat the whole year (so much time and money will go to waste waste). What should I do? 

Q: I shared a pic on whatsapp on which a girls picture was printed and on the bottom it was stated that it is Yahodi sazish. So one member informed me that it was wrong, so I deleted it and sent a message not to share it because it will give me gunah. I tried to message my groups and tell them not share it. If they share it then it is not my responsibility of gaining sin or gunah. I want to ask you that if anyone shares it, will I be sinful because I tried to stop it?

Q: I have a few questions about the eye and pictures.

Q: What does Islam say about taking pictures of someone who has passed away. For example, if someone has passed away in another country and the family can't attend the funeral, is it permissible to take pictures of the person who has passed away and/or the funeral to share with only the family of the deceased? 

Q: With the escalation in the use of social media, we find that people often put up status messages or post pictures with a message addressing a deceased person. For example, a person would post "We miss You, Dad" or "last year this time You were with us" etc. Is this permissible in Islam?
