Ensure all images have alt tags

[roryrabbitfield]

As site editor, I want to make sure all images have "alt" tags. What is the mechanism for making this happen? Some images seem to have alt tags already (which were not manually added by client). The goal is to have the ALT tags make the site more SEO friendly.

Here is what I've found for this task so far:

• It seems like user input images do have alt tags that have been created from the user input content. In some cases this is from a specific field in the frontmatter for the image alternate, in others, the alt i set to the title of the page (mostly in cases where there is one main image that can be set for something like a post)
• There are also many instances where user input images are not inserted as image elements but as background images set in inline styles
  (something like: style="background-image: url("{{ .Params.image }}")")
• It looks like the majority of images with alt tags that are not user defined are things like overlays and logos
  *there is a small portion of the home page (below "Oregon Coast Vacations - Adventure is Our Middle Name" down to the masonry section) that is currently static and could be made to build from frontmatter instead. I'm not sure if this is meant to be a temporary section though
