can you help me. I deleted all the pictures and I don't have a backup on iCloud

Hi, thanks for reaching out. Do you know how long it has been since you deleted these photos and also did you remove them from your library only? Because if so, go to the photos app, tap on the Albums tab and then scroll down until you see the recently deleted text. This section stores all deleted photos within 30 days. After 30 days they will be permanently deleted from your device.
