I sympathise with this guy's anguish, but with something so precious, why hadn't he backed them up?
PCs and laptops break eventually, and obviously laptops can get lost or stolen. Photos on our laptop are one of the few files that I systematically back up to a DVD because I couldn't bear to lose them all. Or you can sign up to services like Tesco photo (I think it's free) and upload photos there - and then you can even pay to have prints made (remember them?)
