These images weigh (altogether) at a considerable size of 5 GB.

Analysis
And with the download links out of the way, here's some analysis on the dataTop 100
Cameras
The most popular camera is the Nikon D800 - a pretty 36 MP DSLR. Next up is the Sony Alpha 7RM2 - an impressive 42 MP Mirrorless Camera. And in third place is the Canon EOS 5DS - a 50 MP DSLR. Pentax seems to have gotten some love (once). While brands like Panasonic, and devices like Smartphones, don't make the list.
Image Resolution
Average (Mean): 7167.51 x 5130.97 = 36.78 MP (Megapixels) ~ 17.7KAverage (Median): 7360.0 x 4912.0 = 36.15 MP (Megapixels) ~ 17.4K
As expected, the largest 100 Unsplash images (by filesize) also have large dimensions - a small amount attributed to "stitched-up" images: panoramas and gigapixel images
The main observation from the graph are that DLSRs with 36MP sensors are popular for producing high-quality images.
File sizes
Total Size (Space): 3.34 GBThe largest image weighs in at a cool 46.4 MB. 8688 px x 5792 px. Taken from a Canon EOS 5DS, by Tikkho Maciel - http://www.instagram.com/tikkho, and uploaded on 2016-03-08.

As most entry Cameras start at 8 MP, Unsplash appears to feature images that have been resized.
File sizes
Total Size (Space): 21.0 MBThe smallest image on Unsplash weighs in at a light 64.9 KB. Its dimensions are 2048 px x 1365 px, is taken by Naveen Chandra (maybe), and was published on 2014-06-16. Given how small its file size is, the image is of reasonable quality. Judge for yourself and feel free to give your own opinion.
Cameras
The Canon 6D rules supreme (in taking lower file size images)!
Smallest/Largest 100
Every one of the top 100 sized images (Lowest = 28.4 MB) is larger than all of the Lower 100 Image filesizes (21.0 MB) combined
