The answer is yes or no. Why?
If the deleted pictures were saved in phone internal memory, the answer will be No. But this is very rare because most of the media files taken in this type of phone are stored on a tiny piece of memory card.
If they were saved on the external memory (mass memory like a SD card, memory stick etc), then the answer is YES.
Then what to do then? By relying on a such third-party image recovery tool, you can get this done though chances of recovery is not 100%. This article has showed how, depending on whether you've rooted your device or not.
How to Do? Connect your Samsung phone (memory card) to the computer first, then install the photo recovery program. Open it and choose the drive your phone card represents and start to scan for the lost files. Then get the found photos recovered easily.
Note: the core of successful Samsung photo recovery lies in whether the data on the phone memory car are overwritten or damaged. So the most important thing you should do is protect the phone (memory card) safe. Even if the phone is broken or wet due to water damage, as long as the memory card is OK, then the data is also OK.
Before Samsung photo recovery, you should remember - Immediately stop take any more pictures or other files with your Samsung phone, or save any more data to the memory card in case you may quite possibly ruin the chances of photo recovery. Once the original photos are overwritten, it is almost impossible to recover.
Update: if this doesn't work out for you, contact Samsung support for more info (they have been quite supportive).
