pictures not showing in gallery after moving to ext sd card

Hey guys, I recently transferred my photos from phone storage to sd card now it is not showing in my gallery. I am pretty certain I found the answer somewhere on here before but I can't find it anymore.

1. The pictures are there in my sd card I can view it in my a file explorer, but it does not show in "gallery"
2. I tried clearing data for gallery and media. I also tried force closing them, still a no go.

Any other suggestions?

Thanks!

Pictures on SD card not in gallery

I just noticed today that my dcim and other picture folders on my SD card are no longer showing up in my gallery. I'm fairly sure they were there yesterday. I'm on a rooted Verizon G4 with 11a software. I haven't made any changes that I know of that could have caused this. I can still access the folders and everything in them using file explorer. Its just not linking to gallery for some reason. Can someone please help with this issue? Factory reset might fix it but I would like to avoid that if possible.

(Questions) Fast Charge and Gallery HIghlight

I have a couple of annoyances that I'd like to see if anyone experiences or knows a fix for.

1. My Fast charging is unreliable. Sometimes I plug and unplug what feels like 20 times before fast charging starts. Anyone else?

2. Every so often, my stupid gallery creates a video highlight file of my pics/videos. Is there a way to turn this off?

Any help is appreciated

Looking for a Gallery app which has live thumbnails and password protection.

As the title suggest i'm looking for a gallery app that has live thumbnails which plays animated media , (Like gifs ,mp4,webm).
I flashed a rom and has a gallery that does that,but that gallery has no options at all ,except from sharing.
I also cant find the name of the app in case there is an update somewhere out and there is an update to it.
The gallery app basically does this: https://vid.me/zXqY and i want something similar with locking function.
