One company asks for picture of my debit card
I don't see a way that this would make matters worse than just giving them the credit card info... Except that it would make abusing the card easier at some other site (or the bank) if they have a similar (unreasonably weak) security-by-photo test. Still, I'd strongly recommend you use a separate card for this so you can cancel it without disrupting your other credit card uses.  (Actually I'd strongly recommend not doing business with folks who have already demonstrated questionable ethics, but you seem to have made that decision.)
