How can I deal with my pictures spread on the internet without a hijab after regretting publishing them and considering wearing it?

A Muslim woman must repent immediately because it is an obligation, and the hijab (definition) is obligatory for her because it helps her maintain chastity and protects her. A woman sending her pictures to a non-mahram (definition) man is heedlessness, and whatever of these pictures can be removed should be removed. If the young man’s request to delete the pictures would cause a greater harm, then do not do it. A Muslim woman should ask Allah for safety and well-being, and she should supplicate with the prophetic prayer: “O Allah, we place You against their necks, and we seek refuge in You from their evils.”
