Image alt tags

[Inkering]

part of a series of accessibility improvements//maintenance taeyoon asked me to work on, I'm going to sort through and make PR's for these where possible

Few of the current pages on the site have images with alt tags. Particular places like class group photos, header images, etc. For specific people pages, I think that it would be nice to add programmatically built alt tags in the jekyll template.
