Are my pics being stored in more than one place & using memory?

[Android Central Question]

I downloaded a pic organizing app (FOTO Gallery). As I move pics, I see them in the new app, but also still in the phone's gallery.
Is this using extra memory? Are they in both? I only want to keep them in 1 location. Can anyone help? thanks!

No it's not using extra memory. The new app and the old one is simply looking at the same place.
