I saw a tool in use and demoed by Venema and Farmer back in NY which they
called "the grave robber's tool kit" though I think it changed names. It
allowed you to "walk your disk" and "look at files" including deleted
ones, and Farmer said he was going to add features to make it allow you to
see images (or what could be reconstructed of an image) for files that
were deleted. This tool may help you do what you want to do, but you
probably don't want to install it on the same system you wish to
inspect. ;-)

It had other features, but the one mentioned here is probably what you
would want it for right now.

Also, if the files are not on disk, but were in memory in unflushed
buffers, and never written to disk, you are probably not going to find
much of anything on disk that was not written to disk in the first place.

Hopefully, others will have other ideas that are better. :-)
