Photos not loading in properly

Barely any of my new images I took today are showing up and I dont know why. I've tried everything I've found like clearing cache in my gallery, restarting my phone, force stopping gallery, etc. but it just won't fix.

All my images are stored in an SD card. I tried moving all of my older images i had before the SD card into it earlier today but some of the images had this same problem, I just thought it needed time to losd but obviously not.

This really upsets me since I really liked the photos I took.
