Pratigya might not tell Krishna...

The fact is even Pratigya also don't know if such photos were taken...she was unconscious for a long time when they took her in the car...so Pratigya could easily get scared if Angad says he has her pictures

I guess that will prevent her from disclosing it to Krishna and she might feel Krishna will get into trouble by fighting with Angad, if she discloses that...last time she herself saw how wounded Krishna was and how he was unconscious for a while...

But Pratigya will feel guilty for indicting Krishna for not his faults...
