Hi no worries, it is possible to recover deleted photos from digital camera like Sony Cyber-shot DSC-W55. You may take a look at this article which helped me last time
Best way to recover digital camera deleted photos
The article gives step by step guide for how to recover photos from digital camera, and the steps are really easy to follow.

SanDisk Rescue PRO 3.0 file recovery utility can retrieve deleted pictures from a flash drive. A little slow but it works great with no degredation.

I don't think you can. Find out if the camera has internal memory if not then the pictures were on the memory card and erased when you hit delete.

Take the memory card to a data recovery company (check phone book or search on line). Most proably they will be able to recover the photos for you. But it will not be cheap.

There are lots of recovery programs available on the Internet.  I used Zero Assumption Recovery very successfully - and recovery of pictures is FREE.  Good luck.
