Slideshow app that will pull from my SD card?

Is there a slideshow app that will pull the photos from my SD card?
I an running Android 4.4.2 from a non-rooted phone.

Does the stock gallery app do this? Or does it not do a slideshow for you?

The source of my problem is that I can't seem to get Gallery to recognise my SD card photos. It will see some but not others. The default Samsung app called "My Files" can see them all, but in a disorganized fashion (not in their folders). An app called "Solid Explorer" can see all photos in their folder structure. I think it has something to do with Google sabotaging Android by taking SD cards out of the picture (pun intended).

I don't have an sd card on my phone now, but have you tried quick pic?
