"GZ2 image file name", what is it? How can one access such images?

"Galactic Rings Revisited. I. CVRHS Classifications of 3962 Ringed Galaxies from the Galaxy Zoo 2 Database" (Buta 2017) is very cool! 😃
Table 2 ("CVRHS Classifications for the Galaxy Zoo 2 Ring Sample") contains the data; column 3 is "GZ2 image file name".
Does anyone know what this is? The paper itself doesn't really say. If you have a "GZ2 image file name", can you use it to get the GZ2 image file it apparently refers to? If so, how?

Yeah, it just gives an image
1 All of the images used can be accessed individually at the URL
http://s3.amazonaws.com/zoo2/filen.jpg, where filen is the number in
column 3 of Table 2.https://arxiv.org/pdf/1707.06589.pdf

any tricks?
GZ2 ran between February 16, 2009 March 27, 2015
Hubble zoo started March 27, 2015
Looking a typical GZ2 post: this one posted in early talk in 2012

from the reference, a typical GZ2 image file name; 108110
Hubble Zoo - ring galaxies http://www.galaxyzooforum.org/index.php?topic=277602.0
typical Hubble Zoo post http://zoo-hst.s3.amazonaws.com/12012184.jpg, it links to an image only
One of the later zoos using SDSS , GZ4 or whatever

No, I can't find a link between image file name and any subject ID, comments and discussion in Galaxy Zoo Talk and Forum.
The sample was selected from the GZ2 database on the basis of the
likelihood of having a ring given the citizen participants’ selection
of the appropriate button. Willett et al. (2013) describe how the
average classifications were determined in GZ2, and at the request of
the author, Zoo members K. Masters and A. Smith sent web links to SDSS
colour images of 3,977 GZ2 galaxies.1https://arxiv.org/pdf/1707.06589.pdf p3

Wow, thanks Budgieye! 😃
That certainly answers my question ... and also demonstrates that my days of assiduous copy editing are over 😦
