If you use SD card you can use application Recuva to recover them but you have to stop using the SD card immediately!
You can also start Gallery and check a Trash:
You can also Galaxy Labs's module File Guardian which prevents deleting files but not retroactively .
I took a load of photos today, stored on my sd card. But they do not show up on gallery view in camera app. But the images are there as I can see them when I connect the phone to my PC. What is going on? Very irritating.
I have the same issue photos taken in 108mp are just showing a black picture.
I see the size 14mp but no image displays.
I have downloaded them to my desktop and they are black.
I cant send the image as its too big but I took a screenshot
