Help finding Sunset images on ImageNet

I’m looking for images of sunsets on ImageNet, to try to build a “Sunset detector” which can tell the difference between sunsets and non-sunsets, but I can’t find any sunset images on ImageNet. I don’t have a lot of experience with ImageNet, so I figured I’d ask here in case someone knows how to navigate it better than I do.

When I search ImageNet directly for “Sunset”, I get:

1Your query sunset is not available yet. ImageNet is still under construction. Please click here to find out what we have.

I then went to WordNet and searched for “Sunset” and got these results:

{15194295} <noun.time>[28] S: (n) sunset#1 (sunset%1:28:00::), sundown#1 (sundown%1:28:00::) (the time in the evening at which the sun begins to fall below the horizon)
direct hypernym / inherited hypernym / sister term
part holonym
antonym
{11538209} <noun.phenomenon>[19] S: (n) sunset#2 (sunset%1:19:00::) (atmospheric phenomena accompanying the daily disappearance of the sun)
{07358615} <noun.event>[11] S: (n) sunset#3 (sunset%1:11:00::) (the daily event of the sun sinking below the horizon)

I tried using the wordnet ID to construct the following ImageNet links:

http://www.image-net.org/synset?wnid=n15194295
http://www.image-net.org/synset?wnid=n11538209
http://www.image-net.org/synset?wnid=n07358615

But in all cases I get an empty result from ImageNet.

ImageNet is focused on objects, and ‘sunset’ is not considered an object. Best would be to scrape google images to get sunsets, and use that to create a sunset detector yourself.
