This was the same problem I faced last April when my sister erased all the pictures from my camera. Those were my weeding pictures and I was really panicking until I heard about www.eprovided.com. My recovery was simple but I tried to recover them from recovery software by myself and things went wrong. I ended up paying $350 but million thanks to www.eprovided.com that I received each and every lost picture. They told me my recovery charge would be $35 if I didn’t made any extra damages with the recovery software. Consult eprovided for 24hrs recovery service.

Hi, don't worry about it. I have used EASEUS Photo Recovery to find my deleted pics which were emptied from recycle bin ever. But they reminded me that don't rewrite on the partition you want to recover from. You can download the demo version to scan your disk and get a fair idea if they could be recovered from http://www.easeus-photorecovery.com/
