Deleted pictures :( help

[JBaa]

Hello,

I have a galaxy s4 mini and one morning all of my pictures from the 'Camera' file got deleted except from 3 random pics. I was wondering if there is a way of recovering all my pictures from that file as I had important memories. What free softwares that are safe to use do you recommend?

Thanks

I've used Recuva before with success.
