First of all check your pictures in file manager. If they are deleted from there too than there is a app which can recover deleted pics or you can recover your pics through computer. Here are both methods.

Through App


Root your Device
Download these app  "Undelete recover files and data"
Allow root access and recover your photos.


Through PC


Download Recuva
Use a memory card reader or connect your Smartphone to PC
Open Recuva and choose your SD card
It will show you all things which can be recoverd.
