You need to sync the uncompressed archives you downloaded from your Takeout. Before you do, though, check out the name parsing settings: you’ll probably want to tweak at least a couple of those defaults (and if you think I should pick different default values, let’s discuss that: is like more opinions to make sure they’re reasonable).
Make sure you uncompress all the archives into the same directory hierarchy, though: Takeout likes to toss bits and pieces of individual albums into different archives.
If you’re on Linux, you can ratarmount to skip the uncompressing step:
I can write down more explicit step-by-step instructions later if this is still too nebulous for you: just ask!
Thanks!
