These are pictures that were deleted from the memory card itself? If so, have you done anyhing further such as saving more data to that memory card? The only hope is a recovery service that can extract deleted data from memory devices as long as nothing has been done since the deletion took place.

If the pictures were deleted from the memory card and as long as you have not saved any more pictures to the card you can use a utility like SanDisk Rescue Pro. This handy utility often comes with a free licence when you purchase some SanDisk memory cards.
There are other programs available if you use Google search.
