iPad - Deleting Photos Without Deleting Them

OK - please explain this to me like I’m six years old.

I have an iPad with a thousand-some photos on it, taking up 6GB of space. I have 20GB of Cloud storage. I do not know how to bridge the gap between the two. I want my photos off my iPad so I can have more room, but I don’t want the photos lost to history. I’m assuming that 20GB of Cloud storage that I’m paying for can hold those photos, but for the love of Og, I don’t know how to get them there.

Again, please explain this to me like I’m six years old.

This article explains it pretty well. Although it doesn’t delete the photos from your iPad, it keeps a low resolution copy to save space.
