Androis Galleriea show no photos/videos topic

Hello! I have a low tier android from att. I just took a picture of my dog and when i went to view it my stock gallery app said there were not pics or videos to be viewed. I downloaded an aftermarket app from thw play store and it claims the same thing. Not too long ago my gallery app would show new pics anymore.
I tried closing it, reopening via gallery through B1 ans file explorer aaand uaing sd rescan. Any ideas?
