Make iphone photos rearrangeable like icons

Hi currently i take business cards with the camera app and save them into my phone as backup from clients and also for easy access.
Is there a way where i can hold down on a photo, then i can drag and drop that photo anywhere else in the album? Like that i can rearrange my photos easily( where it says with the business cards area)
Preferably like how u guys did it with the icons in the springboard.
Many thanks have a great day!
