I am not 100% sure whether Mrs SCUD has deleted the images off of the camera or off of your PC. Either way a nice utility that was recommended to me was Search and Recover which although not free does have a 30 day free trial.
It should do the job for you although you may need to invest in a card reader if you do not already have one but they are not exactly expensive.
I meant to add that Search and Recover can be found
