[NTG-context] Re: images with alt text

[Steffen Wolfrum <context@st.estfiles.de>]

Hi,

today my publishers ask for an example of how ConTeXt deals with accessibility.

I send them a PDF with

\setupbackend[export=yes]
\setupstructure[state=start,method=auto]

What they needed was like
<img src="example.jpg" alt="Example text">

What is the equivalent for this with ConTeXt?
Contextgarden ( https://contextgarden.net/Accessibility) is empty...

Yours, Steffen
