[dba-Tech] Can a "factory restore" be undone?

Hi All,
I had a young mother call me in desperation (because she didn't call me in
the first place ;-) 

Had an infected Compaq Windows Vista PC and boyfriend took care of the
problem for her by restoring it to "factory condition". She's freaked out
because she had 5 years of pictures of her kids on it that are gone now.
(da)

My first hope was that he just reinstalled Windows and the user profiles
would be orphaned but alas, not true. Looks like a clean image has been
written to the partition - I'm assuming that like most consumer PCs, the
factory reset reimaged the hard drive's OS partition from the protected
partition. It does have a protected "recovery" partition.

Any suggestions on trying to recover her photos?
