Accidently deleted important photos from Iphone?

I had some really old photos of my family and friends on my iphone and i accidently deleted some of them! How can i get them back? I have icloud but i never turned the backup on and i don't charge my phone on the computer so i can't restore. Is there any way i could get the photos back?

No there's no other way than icloud or hv sync from laptop.atleast once you should sync it.
Or u hv dropbox? Then pics would be save in it.
