Personalized folders on iphone photos?

So I just graduated HS and it feels like it was all in the past so I want all the pictures I have taken until this point to be in one folder and the pictures I will take from now on somewhere else… What can i do on my Iphone?

Create a new folder, name whatever you want it to be, then copy/move all the pictures you want to be in this folder to it. Then before you delete anything from the original folder, make certain all the pictures copied their original file dates. Then once you have confirmed, then delete them from the original folder.

You could use a computer to sync the pictures (that are placed in a folder) to the phone. So that the camera roll would be free of those pictures but they are still on the phone.

Just placing them in a folder using the phone alone would essentially copy them to that folder & they would still be in the camera roll. So if it is deleted from the camera roll it would be deleted from the album.
