System Syncs A Bunch Of Pictures. Where Do They Come From?

I Installed a new /e/ version and setu up my account. Suddenly there are a bunch of my old pictures on my phone, which I didn’t even have on it before the wipe. None of these pictures seem to be on the /e/ cloud as far as I can tell.
How do I disable this?

My bad, the pictures were not synced through /e/, they were on an SD card I had put into my phone to install the new OS.
