So I opened my gallery and saw that my pictures have turned into blank squares, I tried restarting my Android but it didn't work. All my pictures won't appear and in their places are just blank squares. Help please..

Did you backup these to google drive or similar? Connect your phone to a PC by USB and try to backup your pictures

Are they internal storage or SD card?
