Making accessible graphs in LaTex

Question

Does anyone know how to make a tagged document with graphs in LaTex? I tried adding a comment and a label to a graph, but the .pdf file still fails (missing alternate text) through Adobe's Full Check. I also use Adobe Autotag before Full Check. Thanks!

\documentclass[11pt]{article}
\usepackage[top=0.85in, bottom=1.1in, left=0.8in, right=0.8in]{geometry}
\usepackage{graphicx}
\begin{document}
\includegraphics{img}
\label{fig:img.jpg}

\end{document}

You should be able to add the alt text with acrobat. But beside this you can use the accsupp package:

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{accsupp}
\begin{document}
\BeginAccSupp{Alt={my figure},method=escape}
\includegraphics{example-image-duck}\label{fig:img.jpg}
\EndAccSupp{}
\end{document}

Something similar can be done with the tagpdf package mentioned in the comments:

\documentclass[11pt]{article}
\usepackage{graphicx}
\usepackage{tagpdf}
\tagpdfsetup{uncompress, %for the test, to check the pdf
             activate-mc}
\begin{document}
\tagmcbegin{tag=Figure,alttext={my figure}}
\includegraphics{example-image-duck}\label{fig:img.jpg}
\tagmcend
\end{document}

But attention

• tagpdf is an experimental package!
• unlike accsupp tagpdf hasn't currently different input methods for the alttext key. Its value is handled as verbatim, no TeX commands are expanded.
