I know this isn't a LaTeX list, but with this many physicists there must be somebody who is a LaTeX expert.
I'm trying to comply with accessibility requirements on my campus, and the first step is to figure out how to add alt tags to an image in a .pdf that I created from LaTeX. (I'll worry about equations next, right now it's one step at a time.) I don't see an option for this in the \includegraphics command. I know that LaTeX2html can create accessible html documents with alt tags on the images, but what if I want to create a .pdf rather than an html document? I did a lot of Googling, and I checked Lamport's book, and I found nothing.
