Photo thumbnails

[lorian]

Hello,
I was recovering lost partition data from a 80Gb freebsd disk. The problem is that almost all the photo on the disk are recovered as thumbnails and not in the original format. How can I retrieve the original photos?
Thanks

Files named f*.jpg are jpeg found on the disk, it may included thumbnails present on the disk.
Files named t*.jpg are thumbnails extracted by PhotoRec from the jpg it has discovered.
If the filesystem is fragmented (or if the data filesystem contains indirection block mixed with the data block), fullsize files may not be recovered.
