there's some weird scope/permissions stuff like that I never quite figured out

First World Problems lol

i just want a script to download all the photos people have tagged me in, dammit!

Unsupported get request... I just want a script to download all the photos people have tagged me in.

Maybe the uploaded of the photo would also need to authorize your app?

Uploader, rather.

yea, i assume it's something with uploader permissions/privacy... my script grabbed *most* of the photos i was tagged in, but skipped ones tagged by certain folks. it's just odd to me that i can see photos of myself while authenticated on the site, but not authenticated via API.
