Why can I not find some of my photos since back up

[AC Question]

I had photos of my late dad on here but can't find them which is upsetting and wish I didn't have back up now

Welcome to Android Central! Were they saved to Internal Storage or to the microSD card? Did they back up to Google Photos or somewhere else? Are you sure you're looking at the device folders, as opposed to the cloud? If you're using Google Photos, swipe in from the left and tap Device Folders.
