Need help - some issues with galaxy s5

[STARGATE]

When I went into the application manager to do that the gallery app wasn't under the SD card. I'm a bit confused by this since when I first put it in the camera app said all my pictures will be placed in there and there's even a little icon on the left lower corner of the camera album.

The gallery app normally shows you albums, the Camera album with the SD card icon is the one you want.
