Try recovery tool, it is possible to retrieve lost photos from a phone.
Install it:
Efficient Samsung Recovery Software

From this interface, you can know that, the lost photos are showed in the following interface, so you can connect the phone with computer and begin to recover.

Assuming you're asking about a memory card and you haven't added anything to it, plug the card into a card reader connected to your computer. Do a Google search for "file recovery software" and select a program appropriate for your computer. Hopefully that software will recover your deleted file.

Yes. Remove the memory card and connect it to your computer. Then search the internet for a file retrieval software.

You can often successfully recover deleted photos from a PC, phone or camera memory card or USB Memory stick, it just depends on what's happened since the files were deleted.
When you delete files the data itself isn't deleted, just the index entry that says where the data for those files is located. The space containing the deleted files is also now marked as free space so it is available to the system for any new files to be written there instead.

If and when that happens, then it becomes too late to recover your deleted files so it is very, very important to not save any new files or data to the device concerned.
If the deleted files are on a memory card or USB memory stick, just don't save any new files to it.

One of the easiest ways to see if you can recover deleted files is to try some file recovery software. Recommended this data recovery as it saved my life many times.

Yes, but you will need to purchase a "Rescue" program such as Rescue - Pro, this enables you to search a camera memory card, and retrieve the last images taken.  Beware however that if your son has taken more photos after the ones he deleted then the "Rescue" software may have trouble. 
The best option is to withdraw the camera card from use until you have used the "Rescue" software, to prevent corruption to the image files. These programs are available for down load off the web, at very reasonable prices, or maybe available when purchased with a high end memory card, such as San Disk Extreme IV Series Cards.
Hope this helps Ian

It can retrieve all data from the camera memory and also from the memory card that you have there, if you want to make sure you can go to a photo center and they can retrieve all your deleted photos from the internal memory of the camera and also from your memory card...

Hope that helps..............

Well, no matter you photos in Canon camera got deleted, formatted by accident or became inaccessible due to camera memory card errors. Chances of recovery is possible as long as you take the right action.

Take a try of this software to recover Canon photos, Not only general photo formats, but Canon RAW photo formats (.cr2 or .crw) can be retrieved easily.

Note: before the photos are recovered, Never should you attempt to take more photos or save more data to the memory card in case chances of photo recovery might be reduced. Hope it helps. Regards.
