Earning by taking ID photos

Q: I am currently employed by taking ID photos of people that want to make ID documents or want to renew their drivers licence. Am I commiting a sin? I have no other work to support myself or my family. Currently there is a demand for ID photos in my town. Even Muslim people come to me for photos for passports. Please advice me. 

Eunuchs

Q: What are the conditions of eunuchs in Islam in view of the Holy Qur'an and Hadith if they trust whole heartedly and fulfill such as Kalima, Salaat, Fast, Zakaat, Hajj, etc.? 

Serving special meals to Ulama

Q: If in a gathering where meals are served, there are Ulama as well as non Ulamaa who are present. Will it be against the Sunnah to present normal meals to the general people and special meals to the Ulamaa?

We find the same scenario in the Ijtima where there is a special section for the Ulamaa' wherein extras special meals are served. Will it be against simplicity for an A'alim to eat in the Ulamaa section in the Ijtima?
