Several recovery programs mentioned in http://forums.cnet.com/5208-6142_102-0.html?forumID=58&threadID=213355&messageID=2791858&tag=mcnt might help.
My friend has accidentally deleted all the photos she took on holiday. I am asking for help as she does not have access to the web. The camera is a Pentax optio 60. She did not put the photos on her computer, and says she was trying to delete the ones not wanted and suddenly they all disappeared. Is there any chance of recovering them? I have an Olympus so have no idea how hers works.
