Does one sin if unable to delete personal photos and photos of friends from an image hosting site due to forgetting the password, and what should one do?

"Photography for a recognized necessity or need is permissible by consensus of contemporary scholars, such as photographing for passports, driver's licenses, or crime scenes. As for photography that leads to haram (definition) (unlawful acts), such as photographing immoral people or promoting indecency, it is unanimously forbidden. As for commemorative photography, contemporary scholars have differed on it. Some have prohibited it, like Ibn Baz and Al-Albani, citing the general evidence for prohibition, the danger of extremism, and imitation of polytheists. Others have permitted it. The view of prohibition is considered more cautious and pious for a Muslim."
