One aspect you overlooked is that a hundred years from now today's technology will be archaic. Even if someone wanted to view those scanned photos, their technology may be incompatible.
The more technologically advanced the storage becomes, the less likely future 'archaeologists' will understand them. I think that they will believe that at some point in the near future, these same people will think we vanished for lack of physical records. Some photographs, old vinyl recordings, and printed material may survive and be recognizable, but can you imagine them finding a crapload of plastic disks? (Remember when we used to get the 'Free Month' AOL disks in the mail? I wonder what the future would think if they uncovered a stockpile of those. LOL) The disks themselves might survive, but the data layers probably won't. The surfaces would probably be severely damaged as well.
Removeable media - USB drives, 'thumb' drives, etc - are all vulnerable to corrosion and will eventually become unreadable as well. A strong magnetic field will practically obliterate data in a hard drive (not sure about the new SSDs).
If any do survive, then it becomes a matter of whether or not these future scientists even realize there is something there to recover and have the ability to recover it without destroying it in the attempt.
