Would you be willing to share the albums as zip files or such for downloading? Strangely, google photo albums don't seem to have a method to download the complete album for public albums (there is supposed to be a way to do it for your own albums, though - but that doesn't apply here - though if you were willing to create a download file of the albums, you could download them that way to your google drive, then share the drive files publicly).

Regardless - thank you for sharing these!
