Yep, there are sequences and bits of sequences scattered in this gallery. Judging by the filenames, it looks like a grab from some imageboard and then an upload with the files sorted alphabetically. Since the real filenames got stripped and replaced with essentially random database indices, that also scrambles the file order.

The good news is that CatchABird has an FA account:
