I used to think it's awful for me if I lost the picture of my family or lover. So just in case, I have to use my phone carefully. Unfortunately, iPhone doesn't have a trash bin in which I deleted photos can be stored. But it relieves me that I finally find a good powerful software---iPhone Data Recovery.If you accidently delete photos on your iPhone, here are two ways for you to recover deleted pictures from your iPhone: "Directly scan and recover photos from your iPhone", or "scan and extract your iTunes backup file" to get photos back. As for me, I'm a lazy type, I barely back up my data so first way is my best choice.
