Gallery of Images: Happy People from Our Company Event

Developer: Put explicit user instructions here, such as: "click a thumbnail to download images" or "click an image thumbnail to view image options."

by using the UL/LI html structure, these items have been grouped properly. If another HTML structure was used, additional roles would need to be added.
I have not used the 'title' attribute here, because 'title' has spotty support with assistive technology(AT).
While testing with NVDA + Firefox on Windows, I see that two different methods seem to mostly convey the same information:
- Method One:
  - Add aria-label on the link, leaving the image alt blank and adding role="presentation" to the img element.
  - Screenshot of how this reads out on NVDA + Firefox (Windows) for the first image:
- Method Two:
  - Add all of the information to the image's alt tag.
  - Screenshot of this method on the second image:
This example assumes the following:
- The aria-label/alt text will be dynamically generated and added with some sort of concatenated string.
- the images will have been batch processed for consistency
