Hi
The more you use the laptop the more chance the images will get over written
Ideally you should switch the laptop off.
Then talk to an expert in data recovery
In windows laptops it is usually possible to boot off a linux or windows pe cd or usb
Or remove the hard disk and attach to another pc
With Mac things are more difficult especially the very thin air models
Programs like photorecovery from cgsecurity.org can work on ntfs (windows), ext (linux ) or mac os hard disks.
They scan the hard disk looking for the header information in picture files , office files etc
Then list the files and recover to another disk
The file name is usually lost so you may have to view the image (picture) to find the one you want
Best of luck...
