Welcome to Android Central! Do you remember if those photos were saved to Internal Storage or the external microSD card? If the latter, try unmounting the card (in Settings>Storage), removing it, then inserting it into your computer, and see if you can find the photos using the computer's file browser. The microSD card might have gotten corrupted somehow (which is unfortunately a relatively common complaint when it comes to Samsung devices).
