Hey Nancy, sorry to hear about your missing photos. First, check your Recycle Bin (Windows) or Trash (Mac) and any cloud backups (Google Photos, iCloud, OneDrive). If they’re not there, stop using that drive or device right away to avoid overwriting the data. On Windows you can try a free tool like Recuva; on Mac, Disk Drill or the open-source PhotoRec both work well. Most of these let you scan, preview, and restore common image formats at no cost. If you accidentally deleted photos on your phone, apps like DiskDigger (Android) or an iOS backup extractor could help. Can you let me know what device and operating system you’re using so we can fine-tune the next steps?
