Why are my photos not loading from my gallery?

[AC Question]

Before the new software update I had taken many photos on my S4 that are very important to me. After the new update when I try to open some photos it says "Unable to load image". Is there any way to fix this? I have tried resetting my phone many times and it had not worked

Welcome to the forums. What is really strange is the reset not helping. Unless the photos are in a format that the phone no longer supports.
Can you copy them to your PC to at least not lose them?
