Some doubts about Indian passport surrender/renunciation.

[april2014_AINP]

I am planning to book an appointment and submit in-person.

1. Do I need to get demand drafts for in-person submission? Or can I pay all the required consular, BLS, etc. fees with a debit card?
2. Is it possible to get photos taken there?
3. Does the photo need to be uploaded online with the online form? If so, how? It's written in the booklet to upload the photo, that's why I'm confused.
4. How to attest the photocopies? Is there a specific format, or just a signature and date? Any particular ink colour?
5. Anything else I'm missing? Envelopes, etc.

I called them up and they said photos can be taken there. But the woman on the phone didn't seem confident about the other doubts.
Thank you.
