Which areas folder?? There's device storage and the sdcard storage. There would be a dcim folder in both..so go to the one you didn't delete and transfer em over or copy them(I hope I'm understanding your issue correctly)
also .thanx for being a part if df..I see you joined a year ago on Christmas...
Had the same thing happen to me but luckily all were saved on Google+. I had to log on from a computer to Google+ and was able to retrieve them. Not sure where they go when you delete them so hopefully you were having them saved to Google+.
