LaTeX: images and diagrams in LaTeX

Images and diagrams present the biggest challenge for blind and visually impaired individuals. All information they contain must be verbalised and presented in a way that can be understood by the screen reader. Also, the logical connections between the main text and image must be maintained.

Alternative text

Use the command \Description[<short description>]{<long description>} within each figure, teaserfigure, marginfigure or table:


  • \begin{figure}
  • \centering
  • \includegraphics{Apple-trees}

  • \Description[A meadow with apple trees]{A meadow with eight tall apple trees at sunset. The apples have not yet been harvested.}

  • \caption{Apple trees before harvest}
  • \label{fig:Apple-trees}
  • \end{figure}


Image caption or numbering


  • Use the \caption function (see also the above example under alternative text).

The software automatically numbers the element.
