Is sharing personal images considered sinful?

Assalamu alaikum, everyone. I'm reaching out because I've been carrying this guilt from my past and it's really weighing on me. When I was younger, I posted some inappropriate photos of myself online. Looking back, I feel so much shame and regret about it. Back then, I was just not mature enough and was going through a tough time emotionally. I guess I was looking for some kind of approval or attention in all the wrong ways. Now I understand how mistaken that was. I've done my best to delete those pictures and have sincerely sought forgiveness. I've prayed Salat al-Tawbah and constantly make dua to Allah, trusting in His mercy and compassion. But honestly, my heart still feels heavy. I can't shake the thought that maybe those images are still out there somewhere, or that someone might have saved them. It's especially hard thinking that I might still be accumulating sin if others are viewing them, even though I deeply regret it and have tried everything to remove them. I really want to find peace after my repentance and move forward, but my past keeps haunting me. Any Islamic guidance or comforting reminders would be so appreciated. Jazakum Allahu khayran.
